Hi Sam,
To answer your question it takes a while to learn about the different types of wood. As you try different types you will see some cut easier, some stain better and some just look nicer. You will discover your favorites. You have already noticed how pine is easy to cut (because it is so soft) but it stains blotchy (sp?). It is always available and cheap and great if you are going to paint your project.
A good hardwood to try is Poplar. You can buy it at Lowe's or Home Depot, it is relatively inexpensive and stains well. It cuts good and it is probably my favorite for all those reasons.
Keep your eyes open and you may find wood (cut-offs) at cabinet shops and yard sales. You can always buy wood online. I use Sloans, the link is on Rick's website, and a lot of folks use Ocooch, also on Rick's site. It is like anything else the better the wood the better your projects turn out (usually
. Just start cutting and you will be surprised what all you will learn about wood.
