As a novice quilter having begun last fall, under the direction of my sister who has been quilting for 30 plus years, I keep in mind a bit of advice she gave me. She advised me to finish one project before you begin another if at all possible. She told me that if I have another project in mind, by finishing the one at hand I will keep my motivation to finish. It works for her. Although this is still new to me, it is so far working also. I am making 9 quilts this year for birthdays for my 9 grandchildren. I find myself always anxious to begin the next one. I hope you get your motivation back, but you may also just need a break. My sister is on a break now and enjoying it. What works for one does not always work for another.
