I created these from IKEA home dec weight fabric – the same fabric I used for the tango dance shoe bag. I used white twill for the inside and cut “windows” framed with grey store bought binding. it was a challenge to sew the binding on the windows, particularly where the circular top meets the straight “window sill”. The end result is two washable liming spots for the birds, and a very relieved bird owner. My sister got a rare shot of both Pickles and Bubbles liming together above – they are just too cute!
