I have recently discovered Pinterest... you may be seeing a lot of stuff here from Pinterest!  Like this really cute way to mend tears in your kids clothing.  It's a great way to use up all those small leftovers from your sewing projects, too!

I think it's pretty easy, even a novice seamstress could do this one!  Just be sure to keep the back side of the jeans free from your needle!  Putting a piece of heavy plastic behind the fabric would make this real easy.  Good luck and enjoy your mending!
