Yarn is the foundation for woven fabrics. It comes in all shapes and sizes: small, large, straight, loopy, fuzzy, etc. Where warp and weft meet, fabric is created. Typically smaller yarns are used in the warp. Beams of the yarn are made on a warper and then taken to the loom. Rapiers take the weft across in the interlacing of fabric. I feel like I am writing poetry. And, to see fabric weaving is like poetry. It is amazing to see the two things when seen separately are kinda boring, but together are magical.
