10 shafts are great for weaving 8-shaft patterns and a plain weave selvedge or a plain weave block to separate pattern blocks.
Also, excellent for 2-block designs in 5-shaft satin.
I love weaving on a 10-shaft loom, most recently I wove a series of satin damask scarves. I used 2 blocks, each using 5 shafts. When I wove off the first warp in silver grey, I decided to tie on a second warp in the same design, this time in black. That one is still on the loom, but I’ll have photos soon.
