I learned this the hard way, didn't put stabilizer behind the applique and ended up with what you are describing. Now I back all of my applique and satin stitch works like a charm. A lesson learned.

Tanya, are you absolutely sure it's Wonder Under that you are using? I found Wonder Under too stiff for bed quilts, especially when layered. When you say it is lightweight and gives a wonderful feel to the fabric, I have to wonder (no pun intended!) if we are using the same product. Granted, it was years ago that I tried Wonder Under. Maybe it has changed since I last used it??? I can see using it for wallhangings, but much less so for bed quilts.

Great suggestions everyone! I did notice that no one mentioned that sometimes hooping the block helps as well.

It is definitely WonderUnder that I am using. However, these applique quilts are meant to used on top of the bed, not as blankets to really cuddle with. They are more for bedspreads than warmth. I make sure they can withstand the grandchildren playing on them, cats and dogs laying on them and lots of washing, but I fold them down at night and have blankets or other fluffy quilts underneath for warmth. When I'm making a quilt that I want to use to cover with, cuddle with, etc. I don't use so much applique, don't have close quilting, etc. so that it is soft, fluffy, etc. I also don't put as much work into a quilt that doesn't ever get seen - that is always either in the closet or under the top cover. For my best effort I love the results the Wonder Under gives.

I never use a stabilizer, just light weight heat-n-bond..BUT I also can not use a cotton thread..it must be poly or rayon...could have been your thread...

Oh my word! I have so much to learn!!! :/ How am I ever going to remember all these suggestions?!?!? I really appreciate all the help/suggestions you've given me! What great people I'm friends with now!!! :)

I have a satin stitch presser foot to eliminate the bumpy-ness of satin stitching around edges.
