This is quite a simple hack and as all it requires is sawing off a few bits of wood , stapiling them together and if you want, for extra stability building a quick little anchor out of ribbon and stapiling it to the wall and top drawer.
I started off by sawing off the bit on the draw that is protruding from the top (This draw will be the one on the bottom), with a coping saw. By doing this it will be more stable, but it isn’t totally necessary
Then I sawed the bit on the bottom that is protruding from the drawer, I did this as without it I wouldn’t of been able to staple it here, and I thought that it would be much more stable if I stapled it at the sides as well as at the back. This draw will be the top draw.
Now you should staple the backs and the sides of the drawers together with a staple gun or something like that
(Sorry for the bad picture, I took the pictures after attaching it to the wall)
If you want to you could just leave it like that and put it where you want but I felt that it was a bit too unstable so I quickly made a way of anchoring it to the wall with a bit of ribbon and staples.
All you need to do is grab a bit of ribbon and staple one end of it to the top of the top draw then staple the other end of it to a wall or a window sill, but if you are planning on attaching it to the wall then I would recommend using nails to attach it to the wall unless you have a fairly high powered staple gun as I found out that, my wall at least, is too thick for my staple gun.
If you have any questions or ideas to improve this then please leave a comment or if you have tried other things, such as using more draws, then please do comment about it.
