Can you tell what it is yet?

Take one tea towel, any design you like.  This one suited my purpose nicely.

Gather together a tape measure, scissors and a straight edge to draw a line.  I used a box of Cheerios - a ruler is a more obvious choice as it would also alleviate the need for the tape measure.

With measurements to hand, cut the tea towel to size.

Then cut flaps into the strip of tea towel.

(Is it wrong that I felt bad cutting through the chickens?)

Finally, staple the fabric to the front of a nest box and Hey Presto! 

A privacy curtain for the ladies during those moments when a gal likes to be alone.

Pearl jumped straight in, as I had been keeping 'the broody one' at bay whilst I attached the curtain.
She promptly informed me, as nice as it was, her 'peeking preventer' was too short.  So since this picture was taken I have made another that reaches the bottom ledge.

Pearl says that's much better.
