Thanks, fatquarters, that makes me feel more at ease.
And to cloudshadows: Go for it, girl! Be sure you stretch slightly as you quilt the sandwich, I had heard to do that so as I quilted on my DSM, I slightly stretched it using my hands in kind of a spread eagle shape. I was astonished at how nicely the minkee backing looked after quilting!
Thanks to all the quilters here on the board! You have gotten me more comfortable with sewing & quilting than I have been in years.
