Here are my finished shelves which will feature in my portable room. As you can see from the images, the shelves piece together with tabs which then fit into cut out slots. The shelves were quite difficult to make, but referring to my mini model really helped as I could times everything by 6.5 to get the right scale. The shelves require no glue and once all the pieces are perfectly accurate, they slot into each hole quite easily. Overall, I am pleased with how the shelving has turned out as it took so much planning to get right. I have also found some brown tape which helps neaten up all the edges, so I am feel they have a quite professional feel to them.
