Both hats were made using double stranded Malabrigo Kettle Dyed Pure Merino Wool yarns on size US#10 needles. The pattern is by Colinette and the name of the pattern is "Iris". The blue hat was made using Malabrigo's blue/purple color and the other hat was made in the same yarn colorway Autumn Forest. These yarns were a pleasure to work with and quite soft. The colorways are quite beautiful. Presently a set of fraternal twins, girl and boy, are enjoying these hats!
