That’s the problem with recommending blade types and sizes. What works for me, might not work for you. I cut the miniature birdhouses out of many types of wood. I have used Mahogany, Cherry, Alder, Maple, walnut and even pine and cedar. . They all take a different blade size. For me, I prefer Flying Dutchman Polar blades in sizes 3, 5 and 7. For the hardest woods, I might even use. #9. But that might not work for everyone. You have found a blade that works for you, but for me, it doesn’t work. That’s why it’s up to you to figure what works for you!
I have made hundreds of the miniature birdhouses for craft shows. I don’t list them on my Etsy store because each one is different. I can’t imagine posting thirty or fourty different bird houses. The same thing with ornaments.
