Then again, you can do it with just scissors, ($5), needle and thread (another $5); used Goodwill-type fabric or old clothing of 100% cotton ($3-4); and a cheap batting (on sale, small, $8-10) for a total of $20-30; use an old milk carton for a template (cut with your $5 scissors); measure with a household ruler or a school ruler you swipe from one of the kids....it is possible to make a nicely done four-patch for next to nothing unless you really want to make the investment everyone has mentioned. Just sayin'.....
