I've just finished my first machine quilted baby quilt. It's a bit of a disaster and wish I had hand quilted it. I have a Janome and walking foot. I hand basted the quilt. The basting threads got tangled in the foot and kept pulling so that some of the stitches are uneven. Although the back looks ok, the front has a few puckers. I used Hobbs 80/20 cotton batting and 100% cotton fabric on the front. Maybe the flannel backing was not compatible. I also used Masterpiece thread in the bobbin. I haven't washed it yet so is it likely that some shrinkage will reduce the puckers? I think I will stick to hand quilting.
