What's on the most urgent list!
Is there a deadline? If it's a gift for a certain date, that gets worked on first.
If it's for a holiday that's coming soon, next.
If it's for me, DEAD LAST!
My Grandson get top priority too! I'm currently making a alphabet quilt for his room, a Easter bunny quilt, a train quilt, he loves trains.
Each day when I go to my studio, I set a schedule for myself. I give myself time to work on everything that I have going, with the urgent list top priority.
