Man where do I start? Tempe sales is great! I hav been going there for the better part of 2 decades. I first found them when I worked for a van conversion company that was close to their location. We would often need to match specialty fabrics or different pieces and parts that were almost impossible to find, that is unless you knew where Tempe sales was. Quite often they would make miracles happen and find crazy looking fabric that matched, they have thousands and thousands and thousands of miles of fabric.
On another occasion I broke my lucky guitar strap and was in a panic. I took it into Tempe sales they Easily found the material to fix my strap. 16 years later I'm still using the same strap.
Long story short if you need help with fabric for art type materials give Tempe sales a try before giving up.
