Took my long awaited (I've been gathering my courage) into free motion yesterday. While I didn't notice any tension problems on the block I've been practicing on, I'm having problems with the quilt. It looks okay on the front, but on the back it's as if the top thread is too loose (looping underneath) and the bottom too tight--despite my adjusting the tension on the top thread. It manifests itself on curves. (I'm stippling.) Any ideas?
