I definitely stack cut my inlays. I use 1/32" drill bit that buy on e bay. I am using Pegas Modified Geometries Blades. I have tried every brand but it is my favorite. Size #1 on my inlays. Just about everything else I use #5. My go to filler is Famo Wood. It comes in several wood colors. There are many here that have much more talent and expertise than I when it comes to scrolling and inlays...........just thought I would share my two cents worth.
