((( Brenda ))) I'm pretty new to quilting and really understand the frustration, it begins to just seem like a bunch of work -- but then I'll have a good day and things go together smoothly and I feel so proud of myself for sticking with it, and making something pretty -- and it's a wonderful, fun hobby again...
I hope this passes for you, I think it will, something really attracted you to quilting to start with, and got you through 13 quilts in spite of all the struggles!
I think everyone has given you good advice, I especially agree with taking a break from all things quilting for a while, long enough to miss it and remember why you enjoyed it to start with.
