You can transfer a graphic on any wood piece of your choice, including a frame, top of a table, etc. The surface should be clean and big enough for the graphic paper. I am also sharing a video tutorial here that explains in detail the process of transferring any graphic to a wooden surface using a freezer paper. Just gather the items you need and follow this video to carve your favorite designs on your favorite wood items.
Some tools required to build a picture frame are a table saw, miter saw, measuring tape, wood glue etc. A table saw with a backing board and miter gauge can be used to get the right angle and lengths of picture frame every time. You can use builders square to arrange the final cut pieces before nailing, screwing or gluing. Check out the video tutorial below for more details.
The shelf in the first picture is made of red oak plywood. You can choose the wood type, color and design as you like for your project. In case if you need more help understanding this project, you can refer the source link below. It discusses various items used, steps and tips and personal experience of the author who personally built a Zigzag shelf.
Typically furniture such as tables and chairs is made using solid stock from hardwoods due to its strength and resistance to warping. Additionally, they also have a greater variety of grain patterns and color and take a finish better which allows the woodworker to exercise a great deal of artistic liberty. Hardwoods can be cut more cleanly and leave less residue on sawblades and other woodworking tools. Cabinet/fixture makers employ the use of plywood and other man made panel products. Some furniture, such as the Windsor chair involve green woodworking, shaping with wood while it contains its natural moisture prior to drying.
