One of my favorite fabrics to re-purpose is men's dress shirts. The fabric is soft from being worn and washed, and no matter the size, there is a lot of fabric in a long sleeved dress shirt. Previously Andy did not dress up for work, so I only had some goodwill shirts to work with. Andy's dad wears a blue shirt to work every day(I think), so I mentioned I'd be glad to take the worn out ones, and now I have some great fabric!
I made this stocking advent calendar for the kids with one of Grandpa's blue shirts and some clearance Christmas fabric.
I got the idea from a book or magazine I was browsing in the library. I thought it would be cute to put a little toy or chocolate in each day for the kids, but I had no idea it would be such a hit with the kids. First thing they do every morning is check to see what is in the stocking.
