Here's a question or two to think on while you are trying to decide about which wood to use:
Are you going to paint or stain your wood?
- If you are going to paint, then you can use just about anything.
- If you want to stain then you may want to look at hardwoods, like oak, or cherry, etc.
Do you want to have screws, nails or biscuits connecting the canopy?
- Screws can hold the wood together wonderfully, but soft wood allows for the screws to sink. Again, if you are going to paint the canopy, then I would sink my screws in, put wood filler over them and paint over that.
- Nails work well and used with glue will give you similar results to screws, however you will have an easier time if you plan on staining the canopy.
- Biscuits,
IMO would work best, but it is expensive and somewhat time intensive. You also need a biscuit jointer or plate jointer, which can be an investment. This, I think, would be an option for you if you were going to be doing a lot of woodworking in your future. Otherwise I would go with screws or nails.
In regards to what you can use for wood:
- I like to use Trim for the edges, it is light, and it comes pre-cut so you do not need to use a router. To get the angles for corners, you can purchase miter boxes for less than 20 bucks at your local hardware store. Granted they are not the top of the line models.
- You also can purchase 1/4" plywood, usually in your necessary wood veneer (oak, cherry, etc) at a Lowe's or Home Depot for relatively cheap. this is easily cut, either at home or at the store and then just nailed or screwed to your edges.
I hope that this helps.
Please keep us updated as to what your progress is.
Good Luck and have fun.
