This is super easy if you have one (or a cell phone) you want to cover to keep protected. I just chained the length, did 3 sc on each end of the chain with sc down each side of the chain (one complete round of sc). The first 3 sc produced an extra opening for my earbuds (perfect). Then I did rounds of dc. I did the last row in sc because it would fit better and not be too long.
Yep, my player and earbuds are pink. They only had a pink player and later I matched the earbuds to it.
