Material stiffness
Wood works for a lasting first loom; cardboard is treated as a short trial; PVC needs wider supports and light tension.
DIY loom build plan
Enter the band you want to weave and the material you can actually buy, then check whether the frame, pegs and tension release can carry the warp before you cut or drill.

Build checks
Wood works for a lasting first loom; cardboard is treated as a short trial; PVC needs wider supports and light tension.
The planner compares warp width and peg projection against the chosen peg diameter so thin pegs are flagged before they bend.
A sliding tension peg or slot is placed near the front so the finished warp can be loosened without forcing the band off the loom.
The H/U route starts at the heddle peg, alternates through the open shed path, and points back to the generator and yarn calculator.
