I saw this idea on Pinterest a while a go and have wanted to make it for our spare room for ages. So finally decided it could be my holiday project these holidays. I realise it is a popular idea as it is featured in The Big Bang Theory TV show, however I am not into the show at all and just thought it was a clever idea for a square tissue box cover. I have now thought of a few other ideas such as a liquorice all-sort or video game motifs, using the same technique.
Both these tutorials were helpful: Yarn Games and Elizabeth Wendland
Using plastic canvas from an art shop, I just measured a tissue box and made my squares to fit. Annoyingly I couldn't fit all sides onto one piece of plastic canvas! And had to buy another piece for one square! Then embroidered two lengths of yarn to create the coloured squares. I wasn't too fussed about the order, however kept the colours pretty even. I did use Yarn Games tutorial as reference. It isn't technically solvable, which is a bummer. (Same colours can't be next to each other on an edge) Next time I would make it solvable by refererencing a real rubies cube. The hardest part was outlining it all in black. It took the longest, having to thread each hole, which had already been threaded!
All-in-all it was a simple project that didn't take too long and looks great! I already have people wanting one for Christmas!
