I hope this will illustrate how one can take advantage of cardboard characteristics (quite malleable) to shape such things as buttons and wrinkles. It's a very fast, cheap and easy method.
For this example I used the back, observer's seat of the Cub which has very simple shape. The cushion is rectangular, there are some buttons and seams on the sides. The leather out of the factory was usually black, so that's the color I'm going for.
I was aiming at used and wrinkled look.
1. First I prepared and laminated two 1mm pieces of soft cardboard.
2. I sanded lightly sharp edges and corners
3. Next I applied thinned O'glue and when it was absorbed, but not completely dry, I pressed the middle with the spoon shape tool. This was to simulate depression made by observers behind :
I believe O'glue can be replaced with any other glue for paper in liquid form - there are many similar adhesives: Brand Clear Glue, Tombow Mono Aqua, etc.. You should look for a glue which can be absorbed easily by paper.
4. Then using pipetting needle I embossed the buttons. A blunt stylus was used to make all kinds of wrinkles. Again before embossing thinned O'glue was applied to the area. It helped make the cardboard more malleable and after glue dried, preserved the new shape.
5. I used stretched sprue for the seams on the sides. Thin wire will work as well. I used thin CA glue as an adhesive.
6. The seat was painted with mix of black and gray acrylic and got a coat of clear gloss for bit of shine. It can be further weathered with washes, etc. You guys know the drill better than me .
I hope somebody finds it useful...
