I really want to make this as a gift for someone. Could I make this in a 3X size by adding rows across? Do you know approximately how many rows and where I would make the armhole for the 3X?

It is hard to say since I haven't tested the size. The armholes should be shoulder width apart.

Hi , I love this pattern but I’m having trouble with the sleeves/arm hole size. I can’t get my arm in properly, too tight. Do I use an extra large arm measurement? But continue with small size. Will that work? Thank you

Yes, you can make the slits bigger and add extra sts to the sleeves.
