I have a quilting problem that I would like some suggestions from other quilters. I have been out of quilting for a few months and have forgotten this important technique.
I can sew a consistent 1/4 inch seam when piecing. However when I come to the end of the seam it moves over on the last 2/3 stitches so it is less than 1/4 by just a smidge. This is not good when you are doing miniatures. Can anyone help?

try putting a small "ender" piece of fabric before the seam if you're chain piecing. doesn't have to be a big piece, and you can throw it out when you're done.

Good advice above. Another tip is to use your straight stitch throat plate rather than the zig zag one. Another one is to use a thin point of something, like a skewer, to help keep the fabric going straight.:)

Starch can help make things behave, too.

1/4 foot on your sewing machine would help also.

I use a 1/4 foot but I have the same problem she is having. I like the idea of an "ender" and am going to try it.

I use a stiletto to hold the ends of the piece & guide them thru can't sew without it! I have also seen videos where they use long, thin tweezers to hold the very ends, especially in curved piecing.

I used to have that problem because I was going too fast

The stiletto works great for me.

i found chain piecing helped me with that issue... and I also slow down more now near the ends and it helps too.
