Jim, of Oyama Lake Alpaca Farm, made the loom using a square of white shelving and some finishing nails. The outside dimensions of the wooden square are 25cm x 25cm (9 3/4" square). The nails themselves form a 20cm square (8") and are 2.7cm from the edges (1"). There are 21 nails per side (including the shared corners) for 80 nails total. I have no idea how long the nails were, but 3cm (1 3/16") is above the surface and they aren't at all wobbly. There is 1cm (3/8") space between each nail.
Given the stretchy nature of most yarn, the square "shrinks" a little when it comes off the loom. Depending on the elastisity of the yarn used, my squares end up being 7 1/4" - 7 1/2" when finished.
