Ok, so I’ve struggled with my cushions in the 61 Shasta Compact. First I tried to sew some sort of like pillow cases and that just didn’t work well. So I went back to an idea I had when I recovered this vintage metal crib seat.
2. Add the long cushion.
3. Wrap the fabric on top of the cushion the long ways.
4. Overlap it, pull tight and pin it about every 4-5 inches.
5. On the ends fold like you are wrapping a gift and pin.
And Voila! Now my camera shows every wrinkle but honestly in person these turned out great!
