Just finished a DYI of the apron graphics. When I got my pin, the apron graphics were shot (all faded to a light pink, could barely make out the "W" logo, etc.) While I found some vinyl stickers online for $30+ s&h, this was a little more than I wanted to pay. My solution was to carefully measure everything then redesign by hand in Photoshop (probably better suited job for Illustrator, but my PS proficiency is far superior). Once designed, I printed onto high gloss ultra photo paper on my Epson 6 color inkjet then cut out everything with a paper cutter (straight lines) and by hand with scissors (curved lines). After cutting, I ran a fine pointed black Sharpie around all edges to cover the exposed white edges of the paper. Finally, I put some double-faced tape on the back around all edges and in center of each graphic, cleaned the apron well, and then stuck everything in place on the apron. I think it came out well (even tough I did not do color match exactly, I'm happy with how it looks), and I saved myself $30+ even though I had to put a couple of hours of labor into it.
See pics below for before & after. Graphics included: center Williams logo (4x6 paper), right apron triangle (5x7 paper), left apron triangle (5x7 paper), right apron horizontal lines (8.5x11 paper), and left apron horizontal lines (8.5x11 paper). I also printed both cards on the same printer using high quality photo paper.
PM me if you like, and I'll be happy to provide you with the Photoshop files I made for you to create your own graphics (if you don't have PS, I can convert to high quality PNG, JPG, PDF or whatever other format you may need).
