Here is a quick look at 160 shields in process (supporting 80 kits)…
Shields have five pieces: Four from cotton prints and one PUL or polyurethane laminate.
Two pieces of the cotton print make the front at back of the shield (for maximum interest I choose different prints).
The other two pieces of cotton print are for “pockets”. They are folded and topstitched before assembly.

If it is not obvious, this is a LOT of cutting and ironing.

Here I sew again, preparing to ship in 2018.
