Hi Rocky,

Their phone number is 800-571-0021 and web address is
www.pvsaddleshop.com I've just started doing leatherworking myself and been looking for something like this. I'm going to order this tape as I'm always looking for more ideas and methods.
I also ordered a book yesterday from Barnes & Noble called "Packing Iron". I found out about this book right here in the Leather Forum. This book has lots of pictures of old holsters in it. Several good things about ordering from B & N is that there are no shipping charges, you don't have to pay for it ahead of time and if I don't like it... no obligation to buy it.
