So this one time I worked at a fabric shop. It was great times, but it ended. And when it did, they let me take the strip pile home with me. The shop ripped their fabric instead of cutting, which meant when we got new bolts in, we'd rip off a bit to start with a nice ripped edge. We'd use the strips to bundle up fabric or hang stuff, but we could never use them fast enough, so the box of strips became a box and a bag.
And out of that bag, I've made one pretty big quilt so far (it's the "lines and paisley" quilt on the main page. Someday I'll get around to binding it and taking some proper pictures of it.) That quilt got all my favorite strips, meaning what was left is mostly not my taste. So the best way to make lemonade out of these lemons is to add crazy to crazy and cut it up small.
Here's what I'm making, six inch wedges to make up hexagons. So here's a little tutorial of what I've done so far.
The first step is to sew a bunch of strips together. I didn't want to trim anything at all, so I went for mostly straight. Then I starched and pressed the warp out of it as best I could. Since I'm going to cut it into smaller pieces, just getting mostly straight is enough.
The most important thing is to make sure you've got the height you want. I'm going for six inch tall wedges, so I want about seven inches of fabric to make sure I have enough room to trim out the warp.
Then you line up the 60 degree line of your ruler with a horizontal line on the mat and cut. Just be sure to save those end pieces. You can use them later to square up the ends of your rows.
Now line up the other 60 degree line and cut the other side of your triangle. When you do the third cut, you'll be making a triangle with the strips going in the opposite direction, giving you two different looking triangles from the same starting fabric.
Stack up all those triangles and line them up with the 60 degree mark on your mat, making sure the point is on the line (mine are a little off to show you the dashed line).
Now you just have to measure six inches up (easy with a six inch ruler) and trim off your excess fabric.
Be warned, if you aren't really paying attention, this could mean that you trim right on or before a seam. I'm pretty cool with that since I know my machine will sew through any seam I ask it and I'm going to quilt this to death, but if you don't want that, just be mindful of where you seams are when you sew the strips together in the first step.
