This is an amazing and innovative idea for Lego use. I truly love these adhesive base plates that are offered for Lego building products. The are squared, so that makes it incredibly easy to puzzle together on any flat surface. I am not no happy with the size. They are ten inches by ten inches squared, which happen to be smaller than my twelve inches by twelve inches squared table. On the table that I had intended to use these on there is just a small gap where the base plates do not cover. They are also smaller than IKEA's book and storage shelves, which I saw in the demo video online. To cover the entire top of the storage bench that I have, I would need to have another two sets to cover that bench. If you want the baseplates to fit into odd spaces, the instructions in the package are very straightforward to understand. They state, you need to score the plate, in a straight line, with an Exacto knife or utility knife and then break the plate apart as you have designated. The adhesive is very strong and permanent, I would not recommend placing these down unless you are, absolutely, sure of where you want them to be. Once they are on, they are not coming off, at least without damaging the bottom surface. But all in all it is a great way to spruce up an old piece of furniture, while making it useful again for the kids.
