Plenty of squishable texture and not as difficult as it may look.

The video makes it easier to see where to place the double crochets. Once you’ve watched a round or two, it’s easy to tell where they should go.

Mine turned out larger than I’d have liked, but I guess they’ll fit in with the other blocks well enough. I’ll just have to hope so, because I’m not planning to crochet them again in a smaller size…
