For a long time I looked for seamless cube patterns to make for babies but didn’t find any good ones. Finally I saw these on Ravelry while browsing the favorite patterns section. I had never done entrelac before but the pattern is super detailed and walks you through the whole process.
The first cube took maybe 6 hours, but once I finished that the next ones took half the time. I went up a few needle sizes because of the yarn I used.
My 2.5 year old nephew loves to play with them when he comes over. It’s one of the first thing he asks for after playing Mario Kart. 
They’re great for him because they don’t hurt when he misses catching them (which is often!)
Pattern: Simple Entrelac Cubes (Ravelry link)
Needle: 10.5
Yarn: random bits of Caron, Sugar and Cream and Red Heart (I great stash buster!)
