Your best bet, even though you have many patterns already, would be to buy one in the size you need. Especially with the desired sweater being a fair isle.

Tami, Thanks so much for responding, however, I have not seen the fair isles, nordic knits, Lopi sweaters in a size larger than an XL. I am totally at a loss.
I don't object to buying new patterns at all. It's just where do I find them?

Well, if you jump the yarn and needle size, you will end up with a bigger sweater, but you will have to make the necessary adjustments for the length, which will also grow. The first sweater I ever knitted had a Fair Isle yoke and although the directions specified sport weight yarn, I knitted it in worsted. I was 5'2"/110 lbs at the time and the sweater ended up fitting my DH who was 5'10"/180!

However, a search of "Plus size knitting patterns" turned up this site:

Here is a link that might be useful: Plus size patterns

Damascusannie I want to thank you for that website link. I found that they offer XXS patterns for men and I have been looking for a sweater that was sized for that with out having to sit down and figure out the math for reducing a pattern

damascusannie, thank you so much for the terrific Plus Size pattern link. I guess when I do a search, I give too much information and come up with nothing!
Thanks again.

Sue

I'm glad I could help--I was just lucky I think!
