Of course, I have multiple projects going at one time. I have been sewing since I was 10 years old, so I guess that means I have had more than one thing going for like, 35 years!
I have at least 1 quilt in each stage of the process. I am also working on cutting for 3 different postage stamp swaps. This is my hobby (obsession) and I work on whatever I feel like working on. I try not to get myself on deadlines to get things finished - takes the fun out of it for me.
This is what works for me and I am pretty good about finishing things...eventually.
