Are the signs used interior or exterior? Either way be sure to paint both sides. Any wood including plywood tends to warp if one side is finished and the other isn't.
The materials you use a lot of times you can get cheap but takes a ton of work to make it usable. You might consider this when purchasing the wood. Sometimes spending more on materials is the cheaper route to go. I wouldn't think cedar would be a good wood for painted signs however I really don't know the product you are making.
Thanks for the reply. The cedar is just for the frames which are being stained, not painted. If we do any painted frames I will use pine most likely.
See below as an example. This was made using half inch MDF which we painted white and then my wife painted the phrase on with the black paint. I ripped/cut the cedar to my desired thickness & stained it and then glued/brad nailed it around the edges.
My question really is what would be the ideal type of plywood (mdf, pine,birch, something else, etc) for future signs similar to this? Of course we want quality and will be advertising these as "hand made wood signs" so not sure if MDF would turn people away or not. Also not sure I want to be cutting up the MDF constantly in my garage as I do not have a good dust collection system at this point and my ventilation isn't good either. I understand the fine dust from MDF is even worse.
Your comment about painting both sides is interesting to me.. I had never heard that. Can you elaborate on that at all for this type of application? These are made to be indoor signs, either hung on a wall or leaned against the wall on a mantle, table, etc...
Quality, durability, price, weight (in case of shipping) are most important factors (and probably in that order) when selecting best material to use going forward.
Appreciate the input, hopefully the picture helps.
