Just joined the other day. My wife (the lovely goldfishpollywog) has been here a while. I don't sew, crochet, or anything like that (though she does, but you might have known that).
Well, they did teach us crochet in 5th grade, but I've forgotten it in the decades since. I can sew on a button, but it won't be pretty.
Enough about what I don't do, here's what I actually do:
I do basic woodworking and I make lamps. I also make wall hangings out of hardboard (aka high-density fiberboard).
So far, I've built three bookshelves, our son's bed, our headboard, some sci-fi themed wall hangings for our son's room, and several lamps that populate our house.
I wish I were a skilled carpenter or even a handyman-level, but like a good geek, I have too many irons in the fire for me to get too much skill in any one area.
I've been meaning to join for a while so I can comment on goldfishpollywog's projects and maybe even work up the nerve to try something swap-worthy.
Here goes nothing!
