I do a lot of different sewing, but over the last seven years that I have been making quilts, I have mostly purchased fabric for specific projects. I always over buy because I usually prefer to buy yardage versus pre cuts, so I end up with lots of leftover fabric.
I have currently stopped buying quilting fabric until I finish my current Grandmother's Flower Garden. I do have fabric and batting for two more quilts so I have enough projects to last me this year.
I also make kitchen items, zipper pouches and other accessories with my cotton fabric. I recently bought a load of cute flannel prints and made seven pair of pajama pants for myself and one pair for DD.
