This is my go-to travel loom!  It is sturdy, has fabulous plastic teeth and breaks down into 4 lightweight pieces.  A dream!
 
Our Beka 20 inch tapestry weaving frame loom is designed to offer a basic introduction to weaving. Simple to assemble, each frame comes with a set of beams featuring strong plastic teeth for easy warping (20" maximum weaving width - 5 teeth per inch = 100 teeth per end piece), and all the tools needed to weave a 20" wide X 23" long project. Includes complete instructions, two hard maple beams, two dowel supports cross pieces, a stick shuttle, pickup stick, and weaving needle are included.
