It is so tough to want certain fabrics but not know for sure whether or not you should order them. LOL Been there & done that. LOL I always ask myself these questions and decided from there.
1. Can you afford to pay cash for them?
2. Will you be really sorry later if you cannot find them?
3. Have you got an idea as to how you want to use them or a plan for them?
4. If money is no issue, then get to ordering. LOL And enjoy.
