I'll go with that yet. I used a blanket stitch on my machine to attach the appliqués to the muslin blocks. I'm thinking of using a straight stitch diagonally just up to the appliqué on the blocks and maybe stitch in the ditch around the block borders?
Thanks again for your responses. I'm much less skittish about trying the fusible now!
I love looking at everyone's quilts. Mine aren't near as good, but if you would like to take a peek.....These are all lap/crib size. One day I'll make a full bed quilt!
