Bree123 - thank you for the directions. I will have to apply that next time I quilt. I never heard a washing study before. Interesting. You say "I've done less a couple of times with my early quilts and the batting bunched and stitches started to come undone" how far apart did you stitch when this happened? what type of batting did you use in that instance - do you remember?
I ended up 6.5" blocks by time I sewed both ways.
Do the battings that call out can be quilted up to 10" apart not last?
Now I am a little nervous
