Because wood is scarce in the region, the guild members brought cold water dyes with them. The weavers in Nepal use backstrap looms and were not familiar with multi-shaft looms. The members also brought the Nepalese weavers 2 4-shaft looms and some spinning wheels.

As the guild members worked with the nettle, they found that the yarn was too fine and broke when used as warp. To solve the breakage problem, the fine nettle fibre was plied to make it stronger for use as warp. Several strands of yarn were then used in the weft to create more durable placemats and thicker rugs.
