The second reason this is a favorite is that all the plaid fabrics used here were FREE! When I started quilting back in 2002, I read a tip on the Worldwide Quilting Page that if you were a new quilter, needing to build your stash of fabric cheap and lived in a city with a garment district, you might be able to get fabric that was being discarded by cutting rooms for free. My DH is a UPS driver who at that time delivered in Manhattan (NYC) and was often assigned to the garment district. I asked him to keep a look out for fabric being discarded and his instructions were that as long as it wasn't suit fabric (something I knew he could identify) he was to bring it home and I'd figure out if I could use it. One day he came home with a giant black garbage bag full of fabric cuts and these beauties were one of the treasures I found in it. They were probably fabric samples since they were all uniformly sized to about a fat quarter, mostly (what I thought were) flannels and a few in straight cottons. At that time I didn't know you could make a quilt in flannel but I had read that plaids were really useful in quilting and thought the range of colors were too good to let go.
Maybe a few months later, I saw an episode of the "Simply Quilts" TV show on HGTV (it was still on then and what got me started with quilting) and Sandy Bonsib gave tips from her book on quilting with flannel. Now I knew these fabrics could definitely go into a quilt. A year later I purchased a back issue of the April '93 American Patchwork & Quilting magazine (the first issue, I believe). The original "Point of No Return" quilt pattern was in it, designed by Country Threads of cotton plaids in reds, greys and blues with a cream background and a red plaid back. I immedately knew this was where these fabrics would be used.
It was another year later when I stumbled upon a flannel fabric sale at a Joann craft store and was able to get the cream flannel and the backing "flannel" for (wait for it) $2.99 a yard! Snapped them up and thought I'd get right to work on it. Instead I cut out ALL the pieces for the blocks (A LOT of triangles), made a few and then put it aside in favor of other projects. Then last year, wanting to fulfill a personal "one quilt finish a month" challenge, I dug all these out, intent on finishing the quilt and did so! Now I am a big fan of flannel backs and while not all projects will get one I've currently got two more quilts in the works that will have them.
