Brodissime

I’ve been doing more collage with tissue, vellum, and cheap sewing patterns, and I keep hitting the same wall: once I add three or four translucent layers, the whole thing goes foggy and muddy. You lose the crisp edges and the underlayers just turn into gray soup. I’ve tried matte medium, gel medium, and plain water, and I can’t tell if the issue is the adhesive, the paper, or me overworking it.

How do you keep depth in translucent layers without everything turning into a blob? Do you seal between layers, use a different adhesive, or just accept the mush?

I’m pretty new to this, so take this with a grain of salt—but I tried tissue paper over a printed page last week and it went almost invisible except for these cloudy patches. I used way too much matte medium because I was scared it would peel. Is the trick using less glue, or is it more about what paper goes on top? Also, do you let each layer dry completely before the next one? I definitely didn’t.

QuillAndAwl, that cloudy patch thing is usually too much medium, yeah. I switched to applying matte medium to the substrate, laying the paper down, then burnishing with a brayer through wax paper. Way less goop. PressedPetal, are you working on a rigid board or something flexible? That changes everything for me.

FrayedEdge is right about the brayer. I also think “muddy” is often a value problem, not an adhesive problem. If your underlayers are all mid-tone, stacking translucent stuff just makes gray. I keep a few really light and really dark scraps in the mix so the eye has something to grab. Also: test on a scrap with the exact same paper. Boring, but it saves a piece.

QuillAndAwl, yeah, less medium and a full dry between layers. I learned that the hard way. GlueGunGal, that value point is dead on—I think I’ve been blaming the glue for a composition problem. I’m on cradled board mostly, FrayedEdge, so pretty rigid. Maybe I’ll try a piece on heavy watercolor paper just to see if the absorbency changes the fog.

Thanks, everyone. I just tried the “medium on the substrate, paper on top, brayer through wax paper” thing on a small test and it’s way less cloudy. Still a little wrinkly at the edges, though. Do you seal the whole thing at the end with something, or does that bring the mud back? I’m nervous to put a top coat on because I don’t want to wreck it.

QuillAndAwl, top coat is a whole other beast. I usually use a thin matte varnish or just leave it if it’s not going to be handled. If you do seal, test it first—some varnishes darken tissue paper like crazy. PressedPetal, have you tried sizing the paper first? I keep meaning to try dilute matte medium as a size before layering.

I’m with FrayedEdge on testing the top coat. Also, if the edges are curling, weigh the piece under glass or a board while it dries. Not glamorous, but it works. And honestly, sometimes a little wrinkle is fine—it reads as texture, not a mistake.

FrayedEdge, I haven’t sized the paper first, but now I want to. GlueGunGal, the glass/board trick is my go-to for curling. On the paint-over-collage question, there was a good thread about that: 'Gouache lifts when I try to layer—am I just using too much water?' Gouache lifts when I try to layer—am I just using too much water? — worth a read if you’re putting wet media on top of sealed paper. I think my next test is going to be sizing the top layer instead of the substrate and seeing if that keeps the depth.
