Basically what you need for this project are some popsicle sticks (the full sized ones), a hot glue gun, and some stain (if you choose) and some patience to cut the ends of the sticks off. So let's get started!
Your first step is going to be to cut off the rounded ends of your popsicle sticks. Pretty easy just takes a long time and sends lots of little pieces flying around, trust me I still find pieces every now and again. The next step is going to be the staining of the popsicle sticks all I did for this was paint the stain on and immediately wipe it off with a paper towel because the popsicle sticks absorbed the stain really fast. Let them dry for about a half hour or so, by the time I was finished staining, the first ones I stained were dry so it really doesn't take long.
Don't worry too much about the spaces in the top after all you are wanting a pallet look. Keep in mind that this is going to be a little flimsy like this (trust me) so go ahead and cut some popsicle sticks to be glued to the underside of the top pieces (they will be glued directly to the underside of the top pieces so they will be perpendicular to the direction of the top. This will greatly strengthen the coaster.
Finally just set your drinks on it and enjoy!
