If you need a break, take one. Find something else you want to do. If you love the fabrics you have, keep them. There's no harm in it and maybe someday the urge will hit you to use them somehow. Most of all, don't waste your time doing something you no longer enjoy. Do what makes you happy. I have several hobbies I switch back and forth on as the mood strikes me. I'm interested in pretty much everything. My biggest challenge is limiting myself to the hobbies I have.
