I could write a whole post on wood species as each species has unique characteristics and traits. But, one of the most common types of wood used in DIY projects and furniture building is pine wood (a softwood). Pine is an affordable and readily available option at your local home improvement store and it comes in many sizes. I highly recommend using pine for beginner woodworking projects. Then, as you improve your skill, try working with some different wood species!
Instead of using a container to mix a small amount of epoxy, just make a mixing surface on your workbench using painters tape. Simply lay down strips, overlapping the edges so the epoxy doesn’t get on your bench. When you’re done, peel off the tape and throw it away. This mixing surface will work for more than just epoxy, you can use it for wood glue or any other material you need easy access to while working on a project.
