Its normal to get "discouraged" or in the "dumps" about quilting. But it will pass and soon you'll be right back at it. If the quilt you are working on isn't working out, put it away and maybe in 6 or 7 years, you'll want to get it out and finish it. I'm doing that now with my Dear Jane quilt that I started probably a good 7 years ago. I'm finding it fun to put the blocks together and make my "masterpiece". A lot of the advice in this thread is excellent for restarting your sewing urges. Go to a quilt show as well. That is always inspirational.
