I have been disappointed by the lack of embroidered patches for our beloved flying bricks out there so I designed my own and had some made.*
I have two sizes. The large size is about 5.875" (15cm) wide and the smaller size is about 3.5" (8.9cm).
They have a heat activated adhesive on the back which can be applied with an iron, or they can also be sewn on.
Prices are $7 for the large and $5 for the small. Prices do not include shipping.
I prefer Paypal over Nigerian bank transfers.
