These are very easy two needle slippers - one size fits all. The pattern has been around forever - you can find it here. These will probably go to nursing home patients.
I used the Norwegian Star Earflap Hat pattern on Ravelry for these hats, changing the pattern on the brown one to a puppy dog pattern, and on the white one to a textured pattern instead of using another color.
These hats are easy and fun to make and I plan to make more for Christmas presents.
