calculations for yarn change?

[Buddhamom]

I am making a summer top using recycled cotton yarn which uses a size 7 needle. I want to make the same top using a yarn that calls for a size 15 needle for winter to go over a long sleeve shirt. My question is, what is the calculations I need to do to make it work?

I have never done this, but a quick search brought up this page, which I think has the formula (bottom half):

This example shows how to go from bulky to worsted, but you could go the opposite direction easily--just reverse the math. Looks like you'll just have to know your tension and the pattern tension.

Good luck!

I'm not the OP but wow, that wasn't so hard. Thanks for the link.

so what aboutg when it comes time to decrease or increase, would I still keep the numbers the same?

You know, I thought about that after I posted the link. I really don't know. I would probably do a little fudging personally, just sort of see how it's going and estimate from there.

I would *guess* that with a bulkier yarn, you would be increasing/decreasing fewer stitches to get the same overall result, since each stitch will be "worth" more than one of the stitches on a skinnier yarn. Does that make sense?

I guess the moral of the story is to experiment, keep track of what you do, and post here so we can all learn from you!
