A few days ago, I asked the Tapestry list I'm on what unusual wefts they've tried. I thought I should post the ones I've tried.
1/ Cotton chenille: nice to work with, nice furry visual, kept together perfectly. I really want to try silk chenille.
2/ Metal thread: don't know what kind, ok to work with. The metal strip seems to be twined with thin filaments of some sort, then plied. Nice, because you can be a bit rougher beating it in than I would be with metal wrapped around a silk or rayon core.
3/ Rayon chenille: it was multicoloured and came out a nice speckly furry look, but either it didn't pack down well, or the core thread is showing because I have 'lice'. Lots of tufts pulled out. Could be a function of rayon chenille in general, or of this brand in particular.
4/ Moda Dea 'Dream': scraps from another project, long tufts sticking out all over.
5/ Handspun: (by someone clearing not practiced at it-possibly me!), wouldn't pack down at all, though it would probably be fine if it were evenly done.
6/ Boucle:weaves well, would make a great tapestry sheep!
7/ Mohair: weaves well, very 'hairy' looking
8/ I don't even know what this is: looks like a strand of unspun/soft-spun cotton that alternates between thick and thin, and it's stitched into a squiggle with a couple of fine strands of thread (in this case, popcorn-butter yellow -the class referred to it as the "popcorn yarn" which it does look like when woven.
9/Long eyelash yarn. A nuisance to weave, as you have to pull the tufts out as you weave if you want them loose, but it packs down well. Tufts are kind of long though. Not sure what it would be useful for.
10/ Beldings Artsyl for Crochet and Knitting. Apparently vintage thread. I'm having trouble finding out much about it. The Company was well known for silk production, and was founded some time in the later 19th century. They had mills in various locations in the US and in Montreal Canada (which is where this thread was apparently made). I can't find any info on this particular thread itself, though. "Artsyl" suggests artificial silk to me. Feels like it as well.
I HATE this thread with a burning passion. A few of the spools still had their paper strips on, but any one that the strip is off, the thread practically springs off the spool, like wire. Doesn't help that I only have it in pastel pink, pastel green and pastel purple. Bleh. Beats down without any fuzziness, with almost creepy perfection.
11/ Metallic plastic strip from a child's cheerleading pom-pom. Lots of lice. Can only be beaten down in a closed shed (it just springs back up if you beat it in the natural shed).
12/ Short eyelash yarn. I like this one a lot. Looks like funfur.
13/ Very odd yarn. A thick strand of unspun fibres (feels like acrylic), with a thin strand of tightly spun (single) of same, wrapped with a very fine strand, that spirals around the other two. My camera died before I could get a good picture, but some ares look like slightly fuzzy regular tapestry weaving, with scattered areas of fluffiness. Kind of like clouds, if clouds were woven. :)
