My fifth graders LOVED weaving last year (most of them) and several went on
to do second weavings on their own after the class project was finished. We
used Native American blanket and rug visuals as background and designed on
scrap paper first, using geometric shapes (and staying away from curved
lines). These designs were inserted between the carpet warp (with which the
loom was wrapped) and loom before actual weaving began and were an easy guide
for the actual weaving process. I've used a variety of materials including
yarn from home, Aunt Lydia's rug yarn and trai-tex cones--they all work well.
By the way, as you probably know, if you cut the Aunt Lydia's yarn once
across the skein it makes a good 5 ft. length for weaving. I'm going to do
this with my 8th graders soon and hope they'll enjoy it also1 Have fun....
