I am trying not to have too many quilts on the go at once. I count a quilt as starting from when I begin marking up and cutting the fabric. I am however allowed to plan quilts in my head, and sometimes on paper if I'm messing around with designs. And then I end up gathering fabrics for these planned quilts, to be put aside for when I finally start that quilt. Of course, sometimes the quilt doesn't actually materialise, mainly when it's arty and I can't work out a design, or if the list of quilts which need to be made first gets too long.
I plan quilts for a variety of reasons: a baby might be due, or I might fall in love with a fabric, or most often I fall in love with a design idea. What I'm interested in, and the order I end up making my quilts in, are not always the same. But I really will make those quilts I have at the back of my mind! Some day!
