If I was cutting these in 1/4 inch thickness, I would go to an even smaller blade because the patterns contain some pretty delicate areas. My person preference would be a 2/0 reversible blade. but a #3 would work fine also. I would not go to the higher number blades because, though they are heftier, they also are more aggressive and when turning corners on frail places it ups the chances for a breakage. I would suggest that you put your saw speed about mid range, take your corners slowly and while turning corner pull the wood slightly toward you so that the pressure of the blade is slightly against the back of the blade instead of the teeth of the blade. I hope you understand this comment. I think it will help you if you do. You can run a blade all day in the wood and if you do not have pressure against the teeth, it can not cut the wood
