Personally I would go for the larger blocks as I don’t really see that much difference in the pattern and it will be slightly easier to work with the 2 and 1 inch pieces (and you don’t have to make as many blocks). Now if I saw a big difference in the patterns, I would say stick with the smaller, but seeing as the larger really does not look distorted at all, I would go with the bigger myself. Can’t wait to see it!! Where did you get the pattern? I really like it!
