I have a running zig zag templates that I made using small plates. It is on some nylon type of clear material that I got at a hobby shop, but I have friends that use Dollar Store "cutting mats". You can make the same pattern several times and tape them together (I used clear shipping tape) to get the lenth you want. The ones I made curve "out" and then curve in (half circle above and half circle below); First I drew a straight line the lenth of my "template material" then I marked the half way point on both sides of the dish I used (use top half, match the mark on the dish, move it over and use the bottom half). It was very easy to do. I find I use the large one more (about 4 inches across each upper and the same on each lower swing of the pattern). Move the template over about 4", match up the curves and mark the next row. This gives me a simple but very pretty pattern to use for a lot of my quilts. The overall effect is of a gentle wavy line of quilting and it looks good on a wide variety of quilts. It is easy to do on any sewing machine. Of course really large quilts need a larger machine throat; My Janome has a 9" throat and I've quilted a King size quilt on it. Had a lot of compliments on this pattern. Sorry, but I'm not able to post photos; don't know why. I'm electronically challenged
