During the lockdown, Ms Edyta Sitar of Laundry Basket, put out designs of 4 to 8 blocks of this Mystery Quilt every day. We did not know the final design while making the blocks. The entire quilt was completed in 15 days, followed by different borders we could choose from (I chose the piano keys).
It was a lovely experience and something to look forward to during the gloomy days of the lockdown.
