This blank puzzle can be used to create a memory of any occasion: Wedding, bridal shower, birthday or anniversary, graduation, work function, sweet 16, retirement party, family reunion, art project, mother’s day present from the kids. It can be signed like a guestbook or painted across like a canvas. Q. What is included in my order? A. You will receive a high quality wooden puzzle. The wood is sanded smooth on one side and rough on the back to aid you in assembling it in blank state. I will also include a small piece of wood for you to test your pens. Most puzzles get separated in to smaller manageable chunks, placed on a piece of cardboard and then shrink wrapped to make sure that you don’t have to spend hours putting it together from scratch. Q. What pens should I use? A. The standard ball point pens work the best for writing. Fine point sharpies, crayons, range of paints including watercolor, pencils. Things to avoid: felt tip pens, ink well pens, most gel pens, markers. (all of these are good if you are drawing or decorating the puzzle). Q. What should we do with the puzzle after our guests sign it? A. Just like a standard paper puzzle, this puzzle can be permanently glued together by using save a puzzle kits or applying a piece of Matt board with wood glue. Many customers chose to frame the puzzle as such. Personally, I like to put it away on a keepsake box and put it back together on our anniversary. Make sure you take photos of the completed puzzle for your future reference. The puzzle is made out of 3mm(1/8″) birch solid core hardwood ply. It is very strong and has beautiful light grain that is great for writing or painting. Due to the fact that this is natural wood, each puzzle is unique and the wood colors may vary slightly. I hand pick the best looking pieces and keep all grain following the same direction for the best possible look. Since these are cut with a thermal laser, there is slight pleasant aroma of camp fire that will eventually air out.
