How to Press Sewing Projects: 10 Tips for Beautiful Results
Pressing might not sound like the most exciting part of sewing, but honestly? A steamy hot session with the iron can make a huge difference to your handmade clothes.
Proper pressing is the secret weapon that transforms okay sewing into professional-looking garments. It can help shape fabric, set seams, eliminate puckering, and create crisp, defined lines. And the good news is, it doesn’t require fancy equipment or advanced sewing skills.
Whether you’re sewing your very first project or you’ve been stitching for years, these ten essential pressing tips will help you get smoother seams, crisper edges and better-looking clothes.
Why pressing matters in sewing (and why it's not the same as ironing)
First, let's clear something up: pressing is not the same as ironing.
Ironing = sliding the iron back and forth across fabric to remove wrinkles (like you might do with a shirt before wearing it).
Pressing = lowering the iron onto the fabric, holding it in place for a few seconds, then lifting it before moving to the next area.
When you drag your iron across your sewing projects, you risk stretching seams, especially on curved, bias-cut or stretchy areas. When you press them properly, you're sculpting the fabric into the shape you want it to hold.
A good press can:
- Help seams lie flat
- Make curves look smoother
- Shape sharper corners
- Prevent puckering and bulky seams
- Give your handmade clothes a polished finish
10 essential pressing techniques
1. Test your iron settings first
Different fabrics react very differently to heat and steam, so it’s always worth testing your settings on a scrap of fabric before pressing your project. The last thing you want is to scorch or melt your beautiful DIY garment!
As a general guide:
- Cotton and linen usually cope well with higher heat and steam
- Delicate fabrics such as viscose or polyester blends often need lower heat
- Wool fabrics benefit from steam and a pressing cloth (see below)
- Knit fabrics can stretch out if over-pressed
Keeping a few scraps or your project fabric from your cutting-out stage is really helpful so you can test out the iron settings.
2. Use a pressing cloth for delicate fabrics
Some fabrics can develop an unwanted sheen, scorch marks, or even melt under direct contact with the plate of the iron. If you’re sewing silk, velvet, corduroy, wool, or synthetic blends, it’s a good idea to place a pressing cloth between the iron and fabric to act as a protective layer.
Pressing cloths are also handy for fusing interfacing to fabric, allowing you to keep the steam setting on without it going to squelchy, and preventing the interfacing from sticking to your iron plate.
What works as a pressing cloth:
- Cotton muslin or calico
- A scrap of the same fabric you're working with
- A clean tea towel (not terry cloth – it’s too textured)
- Lightweight paper (yes, really – it works for delicate fabrics)
When pressing corduroy or velvet, use a piece of the same fabric face down as a pressing cloth – the pile will help prevent your project fabric from getting squished.
3. Press seams flat, then wrong side, then right side
This three-step process is the foundation of professional pressing.
Step 1: Press as sewn – Before folding or opening the seam allowances, give the seam line a quick press while it's still closed. This sets the stitches into the fabric and reduces thread impressions.
Step 2: Press wrong side – Open the seam allowances (or press them to one side, depending on your pattern instructions) and press from the wrong side of the fabric. Gently pull the fabric away from the seam line with your fingers as you press to avoid creating ridges.
Step 3: Press right side – Flip the fabric over and press from the right side, again easing the fabric away from the seam. This gives you that crisp, flat finish.
4. Shape first, then press
Heat and steam can "train" fabric into specific shapes. So try to avoid pulling a curved area, such as a neckline or collar, into a straight line as it’s going under the iron. Arrange the fabric into the shape you want to create first, before bringing the iron down to set it.
This is especially important for:
- Necklines on shirts and dresses
- Collars
- Curved princess seams
- Armhole curves
5. Use shaping tools
Ironing boards are flat. Bodies are not. Sometimes you need tools that match the curves you're creating.
Tailor's ham – A firmly stuffed, rounded cushion for pressing curved seams like darts, princess seams, and shaped waistlines. Essential for fitted garments like the Noa pinafore or Etta dress.
Sleeve board – A mini ironing board for pressing narrow tubes like sleeves and trouser legs without creating creases on the opposite side.
Seam roll (or pressing sausage!) – A long, narrow cushion for pressing seams open in sleeves, trouser legs, or anywhere you can't fit over a regular ironing board.
DIY alternatives: If you don’t have any of the above, don’t worry! You can roll or fold up a hand towel.
6. Use the end of your ironing board for small areas
If you want to press a small area without squashing the rest of your nearly-finished garment, position the smaller area (collar, cuff, pocket...) on the curved end of the ironing board and let the rest of the garment dangle off it. This way, the iron only touches what you want to press.
I also find the curved end of the ironing board really helpful when pressing curved seams, such as armholes.
7. Hover, steam, and finger press for delicate work
If you’re working with a very delicate fabric that you’re worried about scorching, or a stretchy knit fabric that you don’t want to distort, you don't always need direct iron contact – sometimes steam alone does the job.
- Use your fingers to press the seam open (or to one side)
- Hover the iron just above the fabric and release a burst of steam
- While the fabric is hot and damp, run your fingers along the seam line to set the shape
Be careful you don’t burn your fingers!
8. Prevent seam allowance impressions with card strips
Have you ever pressed a seam and found that the edge of the seam allowance left a visible line on the right side of your fabric? Very frustrating.
A great hack is to slip a strip of card between the garment fabric and the seam allowance before pressing. The card creates a barrier that prevents the seam allowance edge from making an impression.
This works especially well on lightweight fabrics (lawn, voile, silk) or fabrics with a smooth surface that shows every mark.
9. Use distilled water (or iron water) to avoid limescale splutter
If you live in a hard water area, you've probably experienced the horror of brownish water sputtering all over your precious me-made garment. The higher concentrations of minerals in hard water makes irons prone to limescale build up, limescale that they’ll eventually spit out all over your treasured Nani Iro double gauze.
You can help keep your iron steam fresh by mixing tap water with distilled water or special iron water. The latter can also make your clothes smell gorgeous, which is always a bonus.
Also take the time to regularly descale your iron following the manufacturer's instructions. (Okay, so this may be one of those examples of “Do as I say” rather than “Do as I do”!)
10. Batch your pressing to save time
Pattern instructions often tell you to press after each seam. But that doesn’t mean you have to get up from your sewing table and press it then and there before moving on to the next step.
You can save time by batch pressing a few seams at once. Just make sure you press a seam before you sew another seam across it, otherwise you won't be able to press the whole length of it the direction you want it to go.
For example, when making a dress, you might:
- Sew darts, shoulder seams, and skirt side seams
- Batch press all of them at once (after finishing them)
- Continue with the next construction step
- This workflow is much more efficient than sew-press-sew-press on repeat.

Essential pressing tools
Must-have:
- Good quality iron with steam function and adjustable temperature
- Sturdy ironing board at a comfortable height
- Spray bottle for water (adds moisture when steam isn't enough)
Nice to have:
- Tailor's ham
- Sleeve board or seam roll (or a rolled up towel!)
- Pressing cloth
- Iron water or distilled water
- Point presser (for getting into tight corners and points)
- Tailor's clapper (wooden tool for setting crisp edges on heavier fabrics)
- A DIY ironing board cover to put a smile on your face!
Common pressing mistakes to avoid
Using the wrong heat setting – Too hot and you could scorch or melt delicate fabric. Too cool and nothing happens. Always test on a scrap first.
Using too much or too little steam – If your fabric can take it, steam will help shape it and smooth out any puckers. But some fabrics don’t respond well to steam, and it can turn fusible interfacing into a sticky mess, so turn it off or use a pressing cloth if needed.
Sliding instead of lifting – Sliding can stretch out fabric, particularly on curves, bias-cut edges, or stretchy fabric. Lift the iron up and down in a pressing motion.
Skipping pressing altogether – Even beautifully sewn seams can look messy if they haven’t been pressed.
Pressing over pins – Pins can scratch your iron plate and leave marks on fabric. Remove them first.
Final thoughts on pressing your sewing projects
Professional-looking sewing isn't just about perfect stitching – it's about what happens between the stitches. Pressing might feel tedious in the moment, but it's what transforms a pile of sewn-together fabric into a garment that looks polished. So get into the habit of making it a regular part of your sewing.
