The Scientist is notorious for getting holes in the knee of his jeans. I tried THIS method and failed because his legs are so skinny and my machine doesn't have an arm that turns so it's impossible to sew it without sewing the backside to it (or at least impossible to ME). So I came up with a cute no-sew way to make his jeans last just a little longer until full-blown short season.
*ugly iron-on knee patches (I got mine at Albertsons on sale awhile back, but you can find them just about anywhere)
*Cut shape out of patch
*Iron on (with a square piece on the back for reinforcement)
No more hole :)
