Just need to choose a backing now, and to machine or hand quilt it? It's not that big, 106 cm square-ish.
Heart says by hand, time says by machine.
I also got a cushion made for my Mum, for Mother's Day last week. I LOVE how this turned out too, she's lucky I actually parted with it.
I made it with some linen I've had hanging around forever (about 15 years) and some cotton that has also been lingering for ages.
I hand quilted this, sort of following Kate Conklin's advice, thanks Kelly for pointing me in the right direction. I am more than thrilled with the result.
