Hi, my name is Artie, and I’m new here (maybe 2 months) and new to woodworking. This is my first post on the finishing forum. I just made my first scroll saw project (that story is on the scrolling forum LOL). I made a shamrock, with it being Saint Patricks Day, and all. It is 3/8 Baltic Birch from Woodcraft. Do I sand with a fine sand paper (grade/number?) ? Or as I read somewhere else, do I not sand because the plus are so thin on 3/8? Prime with an interior primer, and then paint with an interior house paint? Latex? Oil based? I was thinking a Kelly Green, semi-gloss. Any thoughts/opinions/advice anyone can throw my way is appreciated. Thank you All, Artie
