Tips for layered papercraft cards that nobody talks about

I've been making these for about a year now, mostly Pokemon starters in little box frames for my niece's birthday gifts, and the side-view sketch is the part I skipped for way too long. I finally started drawing my layers on graph paper with each square being a quarter inch of depth, and it killed most of my wasted cardstock overnight. Before that I had a Bulbasaur where the bulb sat so far forward it covered half the face once the frame went on.

One thing I do differently is cut my big background pieces first, not my smallest ones. I find the little details like eyes and fins are easier to fussy-cut with a fresh blade, sure, but if the big pieces are slightly off I have to redo everthing anyway, so I like to know my base fits before I spend an hour on tiny bits.

For foam tape I've had better luck stacking two thinner layers on the back layers and a single layer up front, it gives a natural taper so the character leans back into the frame instead of sitting flat like a sticker. Also a pair of tweezers with a fine tip is worth keeping on the mat, because placing a half-inch foam square with fingers always ends in a fingerprint on the tape that never sticks right again.

Those Cuphead ones must be a pain with all the curved outlines. I do mostly display pieces, around 30 finished cards on my shelf right now, and the one thing that saved my sanity was spraying the finished layers with a matte fixative before assembly. Cardstock absorbs moisture from the air and the edges curl in a frame after a few months, especially in a bathroom or near a kitchen. Two light coats, five minutes apart, flat on a cardboard box lid, and the pieces stay dead flat. Also try a dark grey backing card instead of white for characters like that, the white paper edges basically disappear against it instead of showing as a halo.

Those tiny pieces are the worst, I always cut two or three extras of anything under a centimeter wide. My tweezers have launched more eyeballs and petals across the desk than I care to admit, and good luck finding a black pupil on a dark carpet after that. I just keep a white paper plate on the desk now so dropped bits acutally show up. Does anyone else do the cuphead ones with the rubber hose arms? Getting those to curve without creasing nearly broke me.

The glue thing is what bit me hardest early on. I used regular white glue on my first few cards and the layers warped into little potato chips once they dried, ruined a whole Mario set. Switched to a glue stick applied thin on the very edge of each piece and the flatness stayed flat. For the rubber hose arms, I cut those as one long strip with a spiral of cuts and it works okay but the curve always wants to kink at one spot. Curious if anyone else found a way around that, mine look fine from the front but the sides get janky.

Update: finally tried the glue stick instead of white glue and my last set dried flat for the first time ever, no warping at all. Still losing the war against tiny pieces though, my tweezers keep flicking pupils and little stars across the desk. Do you all cut your spares first thing with a fresh blade, or at the end when you know what actually survived?
