Handmade carved backstrap loom.  These are made from solid wood and are 1/2" thick to 1/4" thick where the patterns holes are located.    Not sure what to start with? Get the 9 short slot. With it you can make bands for 5, 7 and 9 pattern threads. To go with it, I highly recommend Susan J. Foulkes' book "Weaving Patterned Bands" for beginners. It has great information to get you started. (a wonderful customer suggested the line above :) )
A shelac and wax  finish has been applied.   Choose from the following heddles:

The Durham Weaver is a great source for band weaving. This video demonstrates the double hole heddle. https://www.youtube.com/watch?v=qynTGaBZycw&fbclid=IwAR3NoiDZoAtIcfrlpjO3TfOlZIJKuasxjBI6kokFAHMYwFj1a6R7yt2DQm4
