Hi Wombat, I don't think that would work, as double knit or dk weight yarn (22 sts/10 cm) is actually thinner than the worsted weight(20 sts/10cm). Remember that there are two different meanings for 4 ply; in the UK, it is used to refer to a yarn that knits up 28sts/10 cm, but in the US it refers to the worsted weight (20 sts/10 cm). Is your pattern a US one? I'm assuming it is. If that's the case, Your best bet for a substitute to using two strands of your 10 ply, which appears to be the Aussie equivalent to worsted weight. You could probably get away with using a dk/8 ply weight yarn if you went up a needle size or two. Just be sure to do a tension swatch first. If you wanted to use a single strand of yarn, try a chunky weight yarn (tension of about 14 to 16 sts per 10cm/4inches) which I believe for you is a 14 ply. You're best bet is to go by the tension given in the pattern. Something like Cleckheaton's Merino Supreme might work. BTW, if you're ever wondering what the tension of a yarn would be when using it double-stranded, multiply the tension achieved by a single strand by .7 . For a example, the tension of a double strand of worsted weight which knits single strand to a tension of 20 sts/10 cm would be 20 x .7, or 14 sts/10 cm. If you have a link to the pattern, give it to us and we might be able to help.

Very nice.

Ask Donna Loomis. She loves to knit for a little mad money. In fact, she just loves to knit. I like to knit a couple of hours every day. Usually begin and end my day that way. I especially like to make baby and toddler things for friends and relatives. Lots of babies coming this year, so I am just warming up.

Great, Red! He's going to love it...Be sure to post his picture wearing it....(By the way, I love knitted scarves and my favorite color is green) Dorothy
