Hi Everyone, awhile ago I posted a picture of a quilt I was working. I decided on #1 with all borders mitered here is the post Need opinion on borders. Now I'm ready to load my quilt top and want to use fleece backing (it isn't the real thick fleece) with thin batting. I've read that placing the fleece with the stretch going against the leaders (side to side) to help with the stretching. Now my question is, what size needle would I use? I read somewhere to use a size 20, I don't have a size 20. I have 16, 18, 19 and 21 but not 20...any suggestions on the needle size? Also should I be making my stitches bigger or stitch with the normal stitch I've been using...KEEP in mind, that the top is all cotton and wasn't prewashed before making quilt. Thanks bunches for any and all suggestions given.
