When using two shuttles, you’ll need to do something special to catch in the outside warp threads. Here’s what to do:
Check the area where the shuttle came out of the shed— (at one edge of the warp) and notice if it came out under or over the last warp thread.
If the shuttle comes out under the last warp thread, place that shuttle on the woven cloth closer to the reed. See Shuttle A.
If the shuttle comes out over the last warp thread, place it on the woven cloth closer to you. See Shuttle B.
I say to myself: “under, away from me” or “over, near me,” to remember what to do.
Note: If the previous shuttle is in the position where you want to place your new shuttle, slide the previous shuttle out of the way a little bit so you can put this new shuttle where it should be:
away = closer to the reed
near you = nearer the breast beam.
This intertwines the two wefts at the edge and catches the outside warp threads into the cloth.
