Cotton is my warp fibre of choice for many reasons. It's strong, durable and because there is very little stretch, movement in the form of expansion /shrinkage is minimal when your tapestry is removed from the loom.

I personally use a 4ply cotton for smaller tapestries and a DK cotton for larger pieces.
 
A truly versatile fibre that can be used within a tapestry as warp or weft or alternatively incorporated into macrame, knitting or other fibre based projects.
