Hi! Update: I went ahead and got one Hobbs 80/20 batt and one PolyDown batt. I also found two small pieces I'd layered 2-3 years ago when I took a free motion class. One has W&N in it and the other has a very thin poly batt in it. The W&N one is "quilted" pretty densely and feels pretty stiff. I didn't practice much after that and the samples are very primitive! But I'll wash them this week and see how they come out. I'm thinking at this point that I'll use a new poly batt, maybe!! I have two, one is a Poly-fil by Fairfield and the other is by Create-a-Craft, both low loft- 1/4", inexpensive/cheap ones I think I got at Hobby Lobby several years ago. I may wait to see what the two Hobbs are like when they come. If the W&N sample is stiff after wash/dry, poly does seem best for the baby quilt. I really appreciate all the input here and will push on to do this quilt and get braver! Will report when finished!! Thanks again!
