Encore Mega and Mega Colorspun
For those wanting to knit at a big gauge of 2 sts/inch this is a great option for a machine washable at an affordable price.
Encore Mega is recommended at 2/inch on US 15 and each skein has 64 yards. The afghan closeup shown below gives you an idea of how the 5 Colorspun options work up.
The hat patterns shown below each take 1 skein and are free with the yarn purchase.
If you're looking for 100% wool at a similar gauge, check out Lana Grande by Cascade for another very affordable option. We also have Ella Rae's Lush hand-dyed at the store.
