Since you have a bandsaw, and you want to use the wood for scrolling, you could go ahead and cut the wood into planks of a handle-able size and then stack them with stickers in between to speed the drying. With outside storage drying takes roughly a year per inch of thickness. If stored indoors where temps are regulated and humidity reduced, the drying will proceed faster. As Bud said, paint the ends to reduce splitting. You will still need to joint and plane the boards when dry before using them. If the boards are relatively small, they can be planed and jointed with the correct setup on a router.
