Congratulations Zozee, twins are the best. My Dad was a twin and so was my Mom and so far we have 3 more sets of twins in the family. Sadly none of them are mine although I always wanted a set. If it wasn't so old fashioned I'd say Sunbonnet Sue and Sam but you said your DDIL likes modern. The lamb fabric will be great for boys or girls. I know you will find the perfect pattern and I can't wait to see what you come up with.
