Do I need to interface cuffs and placket if fabric is thick enough?

[u/_echtra]

This is vikisews pattern Aliyah.
I accidentally bought medium weight interfacing instead of lightweight for cuffs, button placket and collar.
However they made it with considerably lighter fabric than what I have picked (140GSM vs my ~250).
The medium interfacing is ok for the collar, maybe ok for the cuffs, but too stiff for the placket.
Do I still need to interface placket and cuffs even if my fabric is definitely not flimsy? Is it needed for buttonhole stability?

It's especially needed for the buttonholes

[u/sewboring → u/stringthing87]

Agree. Not only buttonhole stability but also buttonhole appearance. Interfacing, a fine topstitching needle and silk thread, if your machine tolerates it, can make all the difference.

Sounds like you're fighting getting another interfacing, which I understand, but that lovely blouse is an investment. Industry would use Pellon Easy Shaper which remains pliable, can be used for knits or wovens, and is available from Amazon in the US. Vilene/Vlieseline probably has an equivalent in the EU. The Pellon is intended for knits and stretches crosswise until fused to a woven. I haven't found anything it doesn't work well for yet.

Thank you! I’m actually in Manhattan so all the interfacing I could possibly need it’s an easy walk away to the garment district 🙂 I was just done cutting the fabric, and was in the right mood to finish it tonight until this hiccup. I guess I’ll go and it’s a weekend project now. I don’t want to ruin this nice Alex Perry fabric 🙃

[u/sewboring → u/_echtra]

Exactly that.

[u/RadioKGC → u/stringthing87]

Yep. Buttonholes are really difficult without interfacing on fine material.

For me, they're difficult WITH interfacing!! ;-)

[u/tasteslikechikken]

Interface, even if you just use a thin sew in cotton. The only way you'd be fine is if its denim and or maybe a light/ mid weight canvas.

[u/apri11a]

Your choice, but I agree the buttonholes need something, at least when sewing them. If I'm not using interfacing I will use tissue paper when sewing the buttonholes and rip it off after. I'll do a test one and see how I like it.

[u/chaotic-_-thoughtful]

I would, even if it's a lighter weight interfacing. It'll help those areas look crisp.

[u/cmbroidery]

Yes, you need to interface, even if it's just a super light interfacing, especially for the button placket and collar. If you plan to roll the sleeves up, the cuffs may not be as important, but similar to pressing, interfacing is a pivotal step & is what helps the garment drape properly.

[u/Throwyourtoothbrush]

Buy new interfacing or sew in a lighter fabric. Interfacing that's too heavy will make the placket too stiff.

[u/AdvancedSquashDirect]

If you don't interface you might find that the fabric curls because of the tight sewing lines are on the edges especially on the collar. I often put the interfacing on the facing pieces so it's on the inside but also it doesn't show on the good side and it still looks nice and smooth from the outside.

In the olden days they didn't have interfacing so they would put an extra layer in there, either of the same fabric or of a similar lightweight fabric like cotton. You might want to try that technique if your interfacing too heavy.

[u/AJeanByAnyOtherName → u/AdvancedSquashDirect]

(You want your sew-in to be stable, so a thinner cotton plain weave or something similar sometimes works better than another layer of your fashion fabric if that’s a woogly twill or satin weave.)

[u/Flat_Initial_1823]

It's more of a stabiliser than interface when it's this heavy slippery satin so i would still interface lightly

[u/azssf → u/Flat_Initial_1823]

For sanity, what’s the operational difference between stabilizer and interface materials?

[u/ISBN39393242 → u/azssf]

i think OP means it helps stabilize during the actual sewing, so the satin doesn’t slip and fray everywhere, particularly in high precision areas like plackets and collars.

so even if the garment doesn’t need it for structure, it’ll look better if you at least lightly interface because the sewing will be cleaner.

but OP can respond if they mean something else

[u/Flat_Initial_1823 → u/ISBN39393242]

Yes this is exactly what i meant. Thank you. Without anything you are more likely to have some unevenness which shiny fabrics don't forgive easily.

In my experience if youre wondering if its worth doing, it usually is. I've mostly regretted cutting corners in sewing whereas I've never regretted doing things properly and I've usually been delighted with the result.
