At last The Baby Mac is setup and I’m weaving. this is a four harness overshot weave. 3 shuttles ( 2 pattern shuttles and 1 tie down or tabby). I put my tabby on treadles 1 and 2, then leave treadle 3 empty, with the pattern on 4 thru 7. This helps me keep my feet in the right position. Of course this requires 7 treadles.
