When we have different needs we need to select different kinds of woods to meet our needs. For example, thebalsa is light and stong, and depending on the balsa's characteristics, it is most model makers' favourite plywood. When it comes to the birch, it can take any stain desired. And it is widely used since it is very durable and can meet series requirements. The thickness of extremely high quality plywood ranges in 1/32 of an inch to 1/4 inch.

The balsa has been used for a long history. In South America where the balsa is native to, people used it to make boat and raft in the old time. Now, the balsa trees can be found all over the world and are used more widely. Due to its lightness and strength, it is suitable for making models, surfboards and life preservers. And Thor Heyer's successful travel between the Polynesian Islands and South America by a balsa raft has proved the strength ofbalsa wood.

Balsa wood it the primary materials to be selected when we are going to make models, such as airplane models, boat models and other craft projects. The balsa is very easy to cut and carve, and it can be painted on any color as desired. Using balsa wood to make models is much easier than using other materials because of its lightness. And its strength makes the models made by balsa wood is much stronger. So there is no doubt that the balsa is valuable for hobbyists in the construction of craft projects.
