I work on more than one at a time. I do several different things. I appliqué by hand and I take my time because if I get tired I get in a hurry and make a mess. I machine piece most of my quilt tops and I take breaks again when I am sick of making so many blocks alike. For a quick break I make a mini quilt which I can finish in just a day or so. I hand sew in the evening and machine sew during the day. Everything finally gets done. Big quilts go to a LA quilter. I have 3 out now and will bind them when I get them home. I consider these WIP’s and not UFO’s. My U FO’s are in kit form! When I see a quilt I just have to make I put the fabrics from my stash together for it. I keep those in clear plastic zipper bags with the pattern. I note if I need any add’l fabric.
We all do what works best for us and this is what has evolved for me. I am a widow and this hobby has kept me busy and I have met some really nice people who love textiles as much as I do.
