Thanks so much for the folks who made suggestions here and via PM's...I really appreciate it! I'm not sure when I'll get back to it; as I told one lady, I view muslins kind of like getting teeth filled...not much fun, but it will save much pain and expense later on. And I'm determined to get this wearable. I may try comparing it to my already-tweaked Today's Fit jacket (the one I did for SWAP). I didn't try that earlier because the pattern pieces are not at all alike, but the more I've thought about it the more I thought it might give me a little more insight as to what I need to do.
Next up on my list of things to make is the other set of waterbed sheets...and I WILL make something quick and wearable for myself sometime this week, too.
I hope. ;)
