I loved my dad’s slippers so much and need something simple to knit while sick with a head cold. So I’m going to knit some for me but adapted to use aran yarn. Hopefully.

CO 30
Knit across CO. Join in round. Mark first st.
Knit 1/1 for 28 rnds.
Garter for 3 ridges.
Tongue over 10sts, 15 ridges.
3 RS decrease rows
Pick up 17 sts on ea side of tongue.
5 garter ridges
Normal heel decreases plus:
3 toe dec over 10 sts
3 toe dec over 8 sts
3 toe dec over 6 sts
2 toe decreases over 5 sts
Knit half a rnd, grafted.
Found this site more helpful than the Knitty article for grafting.

The pink was heavier than the purple so I have more of that left even though I used the same amount of each yarn.
