I bought some squares and they have those crimped edges.....first time I've used that type of edge. I have brain freeze and I just can't remember what the crimped cut is called.
Anyway.....how do I judge the seam allowance with these? Do I sew quarter of an inch from the end of the little pointy areas or from the all-fabric edge? I am guessing it's the latter.
Hope you understand what I mean.
Thanks.

Do you mean pinked? I don't like them either. If possible I combine a pinked piece with a straight piece and figure the seam allowance from the outer edge.

Yes, I too assume you mean pinked. I agree with Madquilter. Hopefully, they are a little oversized with what you need so they can be trimmed down a bit. Good Luck.

I am with the others, not a fan of pinked edges. They just throw me off my edge.

Yes that's it!.... pinked!....I was trying to remember what the scissors that cut the edges were called...it's pinking shears...could not remember that.
I want to join edge pieces that are both pinked.

I hate those edges. I straighten them up by trimming them to a straighter edge. Pinking to me is for scrapbooking. Never did understand it. still frays if they're pinked.

What matters is the measurement between the seams, not the seams themselves. Sew whatever seam allowance gives you the finished size you desire. You only need to worry about it if it's not wide enough to be a secure seam, and that's not going to happen with a commercially cut square.

Assuming they're supposed to be 4½" finished, take a ruler and measure that width in the center of the square. What's left over on each side will be the seam allowance with pinked edges. From that you'll get an idea of what you're aiming for. Make sense?

hey, martina... great idea!!!

I don't.ike them as they make such a mess with all those little valleys.

I've used them. just place the edges toward your 1/4 inch foot just as you would do with straight cuts. don't push inward as you sew and all should be well.
