I have a sweater pattern that calls for size five needles. I want to use size ten, as the person i am knitting this for likes the larger stitches as opposed to the smaller ones. How can i do this and still get the right size?
Make a swatch. Check stitches per inch. Figure out how many stitches per inch around the body (including ease) for your gauge. Find the size in the pattern that uses the closest to that number of stitches around the body and use that pattern. Hopefully you will find a size that has close enough to the right number of stitches.
