This square twining loom is 20" from corner peg to corner peg measuring across or down. The pegs extend out 1-1/2", at a 1" spacing.
As you fill in the weft from each end to the middle, you can switch which end is up by pivoting the frame on the stand. The bottom is now the top but facing away from you. Then, turn the stand and frame around, and resume twining downwards.
The boards are pine finished with linseed oil, and the pegs are oak with no finish. As a custom order, the boards could be a variety of different woods, the pegs at a different spacing, or the frame at different dimensions.
The loom is shipped disassembled but is easy to put together. It travels well with just the two stand pieces taken off.
