We've all had a pucker or two in our quilting career. Shake it off and move on. Some people call them kisses instead of puckers.:D ​Makes them sound better doesn't it?

then this quilt is a heavy make out session.....

Have you ever noticed... on some clothing there's a tag that states any irregularities are "part of the character of the fabric"?

There ya go.
Don't sweat the puckers... :D

Puckers come from the backing not beinf smoothed out. I use my glass topped dining table and use clamps from Home Depot to hold the sandwich together. Smoothing every time I have to move it to a new section of the quilt. I can still get a small pucker or two if I unpin a too large of an area when quilting.
I leave the puckers, wash and dry it and they don't show as much. I always use high loft poly batting, never had a quilt coming apart yet. I have made over 110 quilts.
All that being said I would leave it and move on.

Did you wash it ? Sometimes the puckers are not as noticeable after washing and drying. I have also used a large quilt label over really bad puckers too. I agree it is still a wonderful handmade item and willbe appreciated for that fact don't be so hard one yourself :)

Have you ever thought about using a frame, such as the Flynn frame?Roll the quilt top,batting and backing on the frame, use water soluable thread, baste with a large stippling pattern, take it off the frame and then quilt it as you would like. The quilt is firmly basted and when you wash the quilt all the basting stitches all come out. Just a thought.

I feel your pain. I had a pucker so bad on the back of a quilt I had to cut it, cut out the excess fabric, and cover it with a strip of fabric the length of the quilt to make it look like intentional piecing. Turned out okay, but it's not something I'll ever forget.

I really like your saying it will be at someone else's house! That way you do not have to look at it and they will not see what your critical eye sees.

I've never spray basted my batting to the backing...a step that was never emphasized as important in any class I've taken. I've been fortunate, though, to have never had any issues with my quilting results, but I'm thinking that my luck may not continue to hold out...soooo, I'm going to start making it part of my sandwiching process. It just makes sense, and the potential boo-boos just aren't worth it.

Would this method work well with using that cuddle fabric for a backing? Bit nervous to use it but I bought it and all I can think of is that it will be hard for it not to pucker!
