no,no,no.....buy only what you like. Speaking from years of experience.
Fabric I purchased on a whim, I have donated or given away.
I can put together a box for you of fabrics you like at a price you would never find anywhere else, promise. Just pm me with your budget and give me more information on what you are wanting to do and I can send you pictures of fabrics to choose from.
Space is valuable and if you discipline yourself now, you won't find yourself with a lot of clutter later. Good luck!
