1) cut a backing fabric a little larger than the piece you want to weave. I usually start with a piece about the size of a placemat and this ends up making six coasters.
2) lay backing fabric wrong side up and then put two layers of batting on top. I use scrap pieces of batting.
3) start weaving your fabric scraps (over/under) right on top of the backing and batting (saves time). I do not worry about the scraps being the same size. I like the way the unevenness makes a pattern.
4) after a couple of rows are woven, I pin the bottom of each row to hold the strips in place and then just continue weaving.
5) once the entire piece is woven with all fabric butted up against the next piece, I go to the sewing machine and zigzag all horizontal and vertical rows. I use a fairly wide zigzag stitch.
6) after the zigzag is complete then I cut them into individual coasters and trim them to size (approx. 5.5" x 6") Next I do the free motion quilting. (The free motion step does not need to be done, but I like the way it makes the coaster/potholder look.)
7) the last step is the binding. I usually have large pieces in my scrap pile that I pull from to make the binding. To make it easy-peasy I use a decorative stitch to stitch to the backside instead of hand sewing to the backside.
I hope I haven't left out too many steps!! If you have questions, let me know.
