Interfacing

There is an awesome post about interfacing on Mauby's website.

I've only just begun exploring any area outside of sewing quilts.

I made these money cuffs for my kids.  Well, the boy ones are for my boys.  I made the girl ones to try to sell.  (A Lemon Squeezy Home has a GREAT tutorial for these lunch money cuffs.)
But this is the first time I've used interfacing, and frankly I didn't know how or why to use it, but Mauby's tutorial is very helpful.  I've bookmarked it for future reference and you should too!
