could just hot glue it together or sew!
Updated 10/12. Corrected Mistakes in instructions and I enlarged seam allowance. I suggest LInen cotton canvas but Kona Cotton works too. This yields one camper per fat quarter or four per yard. Use Acryic paints. I have used them in the past and the paint stays on for years. Place plastic under your canvas fabric(suggested fabric) for bleed through. Don’t get it too wet with paint or it can bleed to other colors. Use a medium consistency of paint. You can even paint it to match your own vintage camper ! Also this can be printed on wall paper or wrapping paper for kids to cut and color! FUN!
