Hi and welcome to the forum. I'm Julie from Texas. If you go to the back of the lumber department in Home Depot, you will find a rack of culled lumber. It's extremely cheap and will work just fine for your practice. I have even found poplar and oak back there that is great for us scrollers since we need smaller pieces, not full boards. I recommend you start with a board and draw some lines on it. Straight, wavy, zigzag, whatever. Use any blade you want. Try them all. You need to get a feel for your saw and find out which blades "feel" right for you. We are all different. I don't recommend buying blades from any hardware store. They are more expensive and substandard blades. Order some Flying Dutchman or Olson Blades. The blades can make all the difference in you control and cutting. Mikes workshop sells a variety pack of Flying Dutchman blades so you can get a feel for the different types of blades. Good luck and enjoy.
