I have the following that may work for a baby boy born earlier this week..
a cotton multi-coloured DK blend
a wool bluesh green sock weight blend, a wool silk teals sport weight blend, the Berroco Sox is much brighter than the venezia sport yarn.
a couple of wool silk Taiyo sock yarns, in a bright greenish with some fun colours thrown in and a more subdued earthen tones.
Hmmmm what yarn to pick, I'm open to suggestions.......
