What spacing is required for quilting? (Primaloft One)
I made a couple projects from pre-quilted PL1 bought from Thru-Hiker a few years ago, it was quilted at 6" intervals. Ayce makes it a point to be informed so I'm assuming that is what the manufacturer wants.
In both directions?
I believe Primaloft Sport does not require quilting?
Quilting at 24" intervals is recommended for large panels of Primaloft Sport. I've always assumed that would be in both directions. That's a factor in quilts but rarely comes into play in clothing, maybe on the backs of larger sized pullovers. I've tended to quilt a tiny bit more aggressively than that ... 18"
