We have all come across images like this at some stage over the years and would happily have used them for firewood. I am also sure that we have seen rustic dog kennels, planter and other goods made from pallet wood, for sale along roadsides. But did you ever think of making some very useful pieces of furniture with the same timber?
Pallet wood comes in surprisingly different wood species and colors which make for interesting variations as seen below:
This piece is the basis for the mirror frame above right but note the different colors and grain patterns.
You can find a lot of inspiration on Pinterest for projects of various difficulty levels. If you have access to a thicknesser or belt sander to prepare the timber you are halfway there. Just make sure you have not left hidden nails in the rough timber. Although there will be nail holes in the timber this can be filled with an appropriate wood fitter or can be left, and it adds to the character of the piece.
Once the timber is prepared and of equal thickness, I use standard wood working methods to join the prepared wood. Due to the thickness, I use the biscuit method with a good wood glue and clamps. However, if you have access to a KREG pocket hole jig the process can be sped up.
Do not skimp on the final finishing. Get your timber as smooth as possible before applying a good quality outdoor clear matt varnish. Make sure you give it a light sanding between coats. I use steel wool prior to the final coat.
If you have access to fairly clean pallets there is an endless variety of weekend projects you can tackle with basic woodworking skills and tools. I am always willing to assist enthusiastic prospective carpenters on pre-arranged weekends.
