I caused the same problem for myself when putting together one of the quilts I'm working on right now. Are you, by any chance, sewing two layers of batting together as well as the two rows of blocks? I ended up having to do that because i had quilted two rows completely and trimmed the batting all the way back to the edges of the rows. I had to very carefully clip away the excess batting, getting as close as i could to the stitching without accidentally cutting it. that didn't get rid of the whole lump, but it made a big enough difference that i could keep going without picking out the quilting to flatten the batting and quilt again.Originally Posted by wilma osmond
i should have quilted to within an inch or so of the edges, then attached the rows. then i should have trimmed away the overlapping batting, leaving only one layer, so when i filled in the missing quilting, i'd have had one nice, smooth layer.
there are so many different ways to quilt as we go. keep watching this topic. i'm sure you'll get many suggestions. at least one will be one that matches your specific situation and helps you find a solution.
