Our group of friends were always coming up with new summer drink ideas and thought this would be a fantastic idea to keep the recipes on hand to make the drinks again and again! 
Easy to do - cut the surfboard out of 3mm (thicker if you fancy but 3mm is easy to cut) paint them up, engrave the recipe directly over the paint - We used paint markers in black to bring out the engrave better. I sealed over with a shiny high gloss varnish. and that's it!
