I am curious...if a pattern calls for a certain yarn and gauge but you can't find the yarn anywhere or want to use something different but all the yarns you see have differnt gauges, how do you know if it will work?
i.e. I have a sweater that calls for a worsted weight yarn and the gauge is 5 sts=1" on size 6 needles. Every worsted weight yarn I am looking at is like 18 sts = 4" on size 7 or 8 needles.
So, do I need to look for a yarn that is 20 sts = 4" on size 6? What if I can't find it? If the gauge is the same on a size 7 or 8 needle for a specific yarn, how do I know how much to order then? Do I decrease my order by a lot or a little?
The needle size and gauge throws me off when trying to determine if the yarn will work or not.
