I crocheted these puzzle balls as Christmas presents for two of my nephews (and was requested to make one for another!) They are wonderful toys for babies and toddlers, and I've seen adults in my family spend a fair bit of time with them too! They are very tactile, and pleasing to fiddle with.
They are made using this pattern from Look At What I Made. You begin by crocheting 24 little cone shapes, before hooking them together to make the squares you see above. These three squares can then be assembled to make the pointy star ball (in the first and last pictures). The points can also be rotated after assembly to make a flat sided ball, such as in the pictures below. This means that not only can the toy be used as a ball, to throw and play around, but it also develops motor skills, as it is disassembled and reassembled, and allows for different colour combinations depending on how it is assembled!
The finished size of these balls is an adult handful, but I am hoping to make one closer to knee height, which can be used as a footstool or floor pillows - just need to save up for some super chunky wool! I made these using Stylecraft's double knitting range. At first, it can be a bit confusing how to assemble this puzzle ball, so I made up some instructions to package with them. I'm sharing it as a free PDF that you can access by clicking the image below, but ask that you use it for personal use only. Thanks!
I really recommend this pattern though. I don't see many of these being made in blogland, and they deserve more attention!
