What type of projects are you making? Quilts, runners, bags, etc? What size fabrics do you have to use for them?
Start with what you are going to make first as the choices are endless. Many of the fabric shops and blogs have free tutorials and patterns.
I like small seasonal wall hangings. Quick and easy to make. Plus they don't take up much storage room.
If making gifts, I use fabrics according to the person's interest. That is always the fun part of sewing.
