Also called frame looms, these are extremely easy to warp and weave: no need for a warping board, just stretch the warp yarn from top to bottom back and forth across the loom. This means of course that your weaving is limited not just by the width of the loom (which is the case with any loom, small or large) but also by the length (or height) of the loom. These frame looms are ideal to make a tapestry to hang on the wall.
WHAT YOU NEED TO START WEAVING WITH A TAPESTRY LOOM:
2 or more stick shuttles
book (such as "Tapestry Weaving") or video ("Tapestry Weaving Level I")
Nice to have: tapestry beater(s), tapestry bobbins
