Support: Adjusting the Shed on a Cranbrook Loom

If the upper shed (raised warps) are uneven:
Raise the threads by shortening the lower lamm cord of the errant shaft.

If the lower shed (sinking warps) needs to be adjusted:
Determine which shafts are errant and whether they need to be raised or lowered (that is, if shaft 2 is the only shaft that is hanging above or below the other sinking warps, fix this one only).  To adjust, either shorten or lengthen the tie-up cord to the suspended (upper) lamm.

Lower lamm = rising shed = red (usually O in the tie-up draft)
Remember: bottoms up!

Upper lamm = sinking shed = black
