I usually concentrate on one project at a time but I have a tendency to start another project once I reach the ready-to-quilt stage. I usually need to think on how to quilt something, sometimes I get stuck and just move on. Currently I'm hand quilting a full size quilt, I have a plan and do a little every day but it is slow going so I am also doing small fun projects at the same time in order to give me some time at my machine and time to be creative in choosing fabrics and design(storage tote for my rulers, sewing machine cover, selvedge pin cushion etc)
