The mystery of blocking barn squares.

Q I have been asked 'what is the round thing I use to block the squares?'
A Garden kneeling pad

Handy use for the reverse side of garden kneeler

I have marked out a square to make life easier - there are 42 of these in the quilt!
(Previously we had a supply of the foam pads from the trampoline - which once they all came off the trampoline have re-appeared in our life in many guises, many craft related uses . . .)
