Each vintage tattoo inspired sparrow measures between 3-5 inches. The design of the birds is based on a stencil I saw quite some time ago and I don't remember where.
It turns out that this seemingly unassuming hoodie was a poor choice of an embroidery subject because: 1. The combination of the knitted fabric and thick screen-printed dots made any kind of marking on the fabric impossible. I had to freehand it entirely. 2. Trying to force a needle through those thick screen-printed dots resulted in some seriously sore fingers. In life and in craft, no pain, no gain, and since I'm pretty hardcore I conquered the dots and through that pain, gained a pair of sweet birdies.
