I've glued the bug blanks on using a slow setting epoxy. I don't like the five minute epoxies because I feel they don't provide as strong a glue joint as a slow setting type. Another problem common to netsuke carving is holding small elements in place while the glue sets. Here I've used cellophane tape. I also often use small spring clamps, rubber bands, string or thread, or whatever I can cobble together. This sometimes requires a bit of creative thinking.

Here are the blanks glued in place. I've waited about four hours since gluing. The slow setting epoxy isn't completely cured yet, but I'll be going back in with small sharp scrapers and removing the excess glue around the outside of the bug blanks. I often find this is the best time since the epoxy is still slightly soft and tacky and is more easily removed without damaging the surface below. However, you do run the risk of weakening the bond. I'm satisfied with taking the risk in this case, since I'll be pegging the ladybugs into the wood to aid the epoxy.

Above, I've drawn in the basic shape of the ladybug's head with a pencil, as well as the dividing line between the wings. I have a number of ladybug photos for reference to get the proportions correct.
