As part of a swap I'm involved with on craftster - sort of an ongoing thing - I claimed a potholder loom to play with. You may remember these from when you were a kid - square with a bunch of pegs to weave between? I know I don't remember having them in England when I was a child, but I've been intrigued by weaving for a while so I figured this was a great way to play around and see how much I'd want to really get into it!
The loom came with a ton of nylon loops, which to me seem completely pointless because it's not like you can put hot things on top of nylon anyway (assuming of course you're going with the original intent of the loom for making potholders). I found a couple of videos on youtube, to get me started and spent the next 20 minutes of my lunch break weaving squares with some vintage wool tapestry yarn in my possession. The resulting woven piece is actually very pleasing and I'm happy with my first attempts at weaving! I don't think I'll be using these first couple of squares for potholders though - more likely to keep weaving a few more squares and then sew them together into something like a bag or pillow. I think that weaving in general has a slightly higher start-up cost than most of the other crafts that I do and I know eventually I would love to make beautiful scarves, pillows, afghans etc. but I may have to work my way up.
