Love your placemats! Your mum will use them with pride.
You mention sewing down binding on machine - for placemats I always do that because you will have to re-sew several times in the lifetime of the mats if you do it by hand - I've learnt from my mistake and I have made umpteen mats over the years :) Thanks for sharing

Beautiful placemats.

Very cool. The way you have them laid out, it would make a great design for a modern quilt.

Super. BrendaK

Very pretty...

They look unique. I have never seen the pattern before. I am sure she will be delighted with your gift.
