From the Knit Picks Website:

I love fingerless mitts & legwarmers and your infant/toddler will too! This set is great for outdoor activities in the cool weather that won’t overheat your special one. They are great for a unique shower gift too!

The knitting level is beginning/intermediate but even experienced knitters will enjoy these quick knits.

Size 1 (2.50mm): or Size 2 (2.75mm) DPNs

Legwarmers Needles:
Size 3 (3.25mm) or Size 4 (3.5mm): DPNs
