I am knitting The “Flex Tee” by Heidi Kirrmaier using the recommended Quince Kestrel yarn. I have gotten gauge on a size 8 needle. My question is I am between sizes. I like the 5” positive ease but my full bust is 35” so i would like to make a size 40”. Which is not an option. The pattern size choices are 37 3/4 or 42. What should I do?
