The back panel template. On the left, I've marked it for tufting (if I'm going to be experimenting, might as well experiment with a variety of techniques, right?).
The front panel template (laying on the cut out pieces of plywood). You can see the holes have been drilled in the back piece, for tufting and the front piece has also but cut.
Because of the thickness of the foam and batting, a longer needle was necessary. Being that the nearest store with the possibility of an upholstery/tufting needle (I don't know its' actual name) in stock is almost 30 miles away, I used what I had on hand - stiff stainless steel wire and masking tape. A workable length was cut, the end looped, and taped to itself to prevent snagging.
The underside. Thick bamboo skewers (again, using what I had on hand) were cut into approximately 3" lengths and used to secure the knotted tufting threads
The layers used were, the 3/4" plywood,
4" thick medium density foam,
I love the look!
