I have two floor looms in my "studio" - a 45" Nilus LeClerc with four shafts and a Schacht Mighty Wolf 36" wide with eight shafts. I've been using the LeClerc loom for about three months and am getting pretty comfortable with it. The Mighty Wolf hasn't been used yet but after I finish the carpet that I'm making now I plan to do my next project using 8 shafts.

I've just started a bathroom carpet. I'm using Maysville carpet warp doubled for the warp and part of the weft. The rest of the weft is 8-ply mop cotton. I'm using a trick that I learned to save time warping - I'm making the warp twice as long as I need and making two crosses. Then, when I take the warp off, I double it over, combine the two crosses and I have the right length with twice the threads. A nice time saver. Here is one-half of the warp on my home made maple warping board:
