Don't give up! I find that making quilts for donation Project Linus, shelters, etc really gives one a sense of accomplishment and a warm, fuzzy feling.
These quilts I don't have to be so fussy about. I also like to make crumb and scrap quilts because then I don't have to be so particular. Take a break and then give it a go again. Good Luck and remember to have fun and enjoy the process.
