At some point someone asked me how I built my shelves, so this is in reply to that. I know it's not figurines, but they'll come after this as I've finally finished building the shelves and arranged my collection accordingly. My explanation may not be the greatest since I'm not technically inclined but hopefully this will help someone out there. Let's get started then.
The first picture shows the support beam that you're going to affix to the wall with screws and wall plugs after you have measured from the ground up where you want to build the shelves. You will have also had to work out the distance between each shelf and the final height that the shelves will be when complete. I had to build it this height from the ground up as there were sockets in the wall and thereby could not build them any lower, unlike my existing shelves which are built from the ground up, and this can be seen later on.

The second picture is to show how you place the actual shelf on the beam that you have just attached to the wall. The support beam is 45mmx20mm while the actual shelf is 300mmmx20mm, except where the shelves have to be made shorter to allow room for the glass, but that's still coming. The lengths are also a matter of choice and not engraved in stone.

The third picture is just to show how we made the shelf level with the wall, and you do this by taking a small piece of parallel wood that fits in the widest part of the gap that appears between the wall and wood (Our walls were built skew (another story) so we had to do this with all the shelves, but if your walls are perfectly flat then less work for you but this will help you in any event should you face the same problem. Anyways, you put it in the gap and using a pencil, draw a line as you move the block across the length of the wood. You then cut or sand off the marked off piece and it should fit, not perfectly, but well enough. Should there still be a slight gap you fill this with sawdust and wood glue.

When it comes to joining your two shelves, first place biscuits as you see in the picture, keeping in mind that the biscuit machine defines where your first biscuit will be as the machine will have to be placed right against the wall, and then you place the remaining two biscuits more or less equally from each other

This is what it will look like once you have made the holes and are about to join the shelves together. Just make sure to put something under the newly joined shelves to avoid getting glue on the lower shelf.

Once the shelves are joined it should look like this:

This picture just shows the second shelf, however it is shorter than the first shelf in order to make room for the glass. We decided that we wouldn't make the glass as big as the first shelves we built for various reasons, so the shelves were divided with this in mind. You are going to place a 20mmx20mm support beam between the three shelves at various points which is what will help you work out how far in the second shelf should be (20mm), but you will see this in the later pictures and may be easier to understand than how I explain it (warned you). We put these support beams in after building all the shelves but there is a chance that the wood may have warped by then, which happened to us, but this is not a complete catastrophe as you will see.

Just a progress shot.

Here you can see the support beams I mentioned, as well as how it is right up front for the top and bottom shelves, but the middle one rests behind it. This space is where you will be gluing the strips that the glass is going to fit in. These strips are about 20mm wide and can only be bought in certain lengths, so you will have to cut them to size as needed. You can buy them at Buschells (Not 100% sure on the spelling, sorry)

The extra pieces of wood in-between are to make sure that the middle shelf doesn't pull up while the glue is drying. This only happens though when the wood starts to warp, which is why we tried to finish building the shelves as quickly as possible because pine tends to do this.

These chrome legs are used to support the majority of the shelves' weight (alongside the beams you already screwed into the wall) and can be bought at Builders Warehouse or Chamberlains. This is not a golden rule as you can also use wood, or some other alternative like a 4-inch steel tube as an example. You can also adjust their height via a small plastic foot at the bottom which is great in case you need to modify its height for some reason (which we did, but we also had to saw it shorter as it was still too long. Use masking tape to cover up where you're going to saw to avoid causing any scratches should the saw slip)

All the woodwork is done, but we still have to put in the strips before varnishing, as the glue won't stick properly if you put them on afterwards.

The Final Product. I hope this was helpful at least to someone. Next instalment, my COLLECTION!
