For our second wedding anniversary (cotton), I made Mark a t-shirt quilt out of all the Old Chicago Beer Tour shirts we collected over our years together. I followed some simple instructions and felt it turned out pretty well! Some of the difficulties I faced while making this had to do with the shirts' patterns not all being placed in exactly the same place or being all the same size. Other than that, really the most important thing was getting all the interfacing on so that the shirts didn't stretch oddly at any point in future use.
