I like to use kebab wooden sticks instead of toothpick, longer and more confortable...I usually cut them in half with 1 pointy end and scuplt the other end as a spatula to use to old smaller piesecs or move them.

I also use carboard boxrs (the thin glosy stuff like cereal boxes) cut about the size of playing cards to mix paint or to put glue to dab with the kebab stick.

I always keep small ziploc bags to put away smaller pieces when i'm done working for a while so i dont loose anything
