My pocket is done. Here's how it all came together.
After "pick pocketing" some museum's collections, I guesstimated the shape and size which I drew on the fabric.
I included a second piece of lighter weight white linen to use as the lining so the embroidery won't snag and catch on my pocket's goodies.
Obviously, I cut it out...
...and made the center slit.
Remember my Fab Fabric Find? I removed the border from two napkins and pieced them together to use as the back.
I then traced the pocket...
...and got ready for the good part: sewing it all together.
I borrowed advice from the V&A's website about making your own pocket. I backstitched the layers together and covered the raw edges with linen tape.
The tricky part came at the bottom of the slit where I tried to meet two pieces of linen tape at the slit's curve.

(By the way, I call it "Polly's pocket" not just for the pun of the children's toy, but because the young woman I interpret was / is named Polly.)
