I just purchased a floor loom which is a copy of a Glimakra loom. (sorry, I don't know the model.) The maker was a weaving teacher who made a few of these for his students,. Which dent would you recomment for a first reed for the larger floor loom? I have used a 10 and 12 dent reed on my table loom so far. (I realize the loom isn't complete in the picture, it is just one of the pictures the seller sent. I have all of the pieces, not yet put together.) Thank you for your help.
