I really like this pattern
but it calls for a size 13 needle and 3 balls of yarn. I'd like to use a size 9 needle, I like the look of stitches with a small needle, but my guess is that a smaller needle means more yarn needed. How do I figure out how much yarn I'll need for a smaller needle with this pattern?
I should add that I'll be using Worsted yarn and figured out it should need 4 balls instead of the 3 the pattern calls for. I added up the number of total yards needed (using the original yarn stats) and divided it by the yards in the balls I'll be using.
