I love watching the crafting videos on YouTube. They are often on in the background whenever I am doing anything.
There are many very creative people out there. My Crates came about after watching Gareth over on DMG. He built a crate, which I thought was a cunning idea, and made my own version of it.

A few weeks later DM Scotty showed an even easier way to make a crate – a wooden cube painted to look like a crate. I thought this was rather cunning so ordered a set of 10 x 20mm cubes and 10 x 25mm cubes to give it a go. The two sets cost about £5.50 with free postage. They came all the way from China with free postage (I still cannot work out how that is financially viable).
Anyway, move forward a few weeks. The dreaded flu struck and my various bits and pieces sat there. Whilst in the recovery phase I watched Dungeons and Gluesticks. John was making crates too (all three videos probably spanned 3 years).
John also used the basic wooden cube but instead of just painting it, he used a razor saw to cut grooves into the cube. He then added the cardstock around the sides. It did look rather good.
I decided to give his version a go last night.

Mine are a bit rough and ready but they do indeed look like crates. I could probably use narrower strips of cardstock on the edges. However, seen on a table a metre away I don’t think it will really matter. I didn’t bother sawing into the sixth face of the cube as I am going to base a lot of them in groups to act as a line of sight blocker and/or cover.
I made another one today on my lunch break.

They are indeed very easy to do; they take a bit of time but look the part and in my mind well worth the small amount of effort it takes to build them.
Below are links to the channels I mentioned above.
