You'll need the Deep Point Blade, a StrongGrip cutting mat, painter's tape, and your piece of wood.
In Cricut Design Space, adjust the material settings for balsa wood. Secure the balsa wood to the StrongGrip mat and brayer then tape the edges down with painter's tape. The machine will make multiple passes to cut through the wood. If it still is not cut through when it's finished, hit "C" to add additional passes. Check the cuts before removing the balsa wood from the mat to make sure the design is cut through. Use utmost care to remove the balsa wood from the mat. It's very prone to cracking and breaking.
