A very fun project!

I made the Small/Medium size and it fits perfectly! If you do want to use Red Heart Boutique please note that for the Small Medium it used up 3 balls completely, so you need to work out your colors accordingly, or have some extra for the contrasting color.

Take note that depending on whether you use the front or backloops on the panels it can make your top interesting/unique! I did the top 3 panels with backloops in the 3rd row of each panel, but swapped it to front loops (as mentioned in the design) for the last 4 panels at the bottom
