I knew it! When I started crocheting here in Australia, I used the size yarn which is most common, 8 ply, but I knew deep down that it wasn't I was used to. It was smaller. But even though I searched and searched I couldn't find a conversion chart to verify my belief.
And then, I got off the internet, browsed the crochet books at the library, and voile! There it is. 8 ply is the equivalent to DK/Light-worsted in US, and I had mostly used Worsted weight, the equivalent of 10-ply here in Aus.
I've set a goal of completing at least one crochet project each month thinking that would be no problem. Well, this blanket that I've started just isn't going to get done in time. The yarn is an 8-ply and I'm working it with only a size F hook. It's 260 stitches across. (Who thought this was a good idea??!!)
So to meet my goal, I'm going to sneak in a small fingerless glove project for my daughter and keep the blanket going into next month.
I'd love to hear from you about your latest project. How is it going?
