I spent part of today tracing off the bottom border and then making tiny circles for "water" in the fountain that is the centre of the border, I think there are about 30 of them. I was looking through my stash to see if I had anything suitable for the "water" and found this fabric (below) which looks as if it might suit.
I'm using Perfect Circles from Karen Kay Buckley to make my circles, although some of these aren't perfect circles. The first ones I made had a little too much fabric to gather, so a lesson learnt. I'm also sewing the running stitch while the fabric is in one piece and then cutting the circles out, much easier than fiddling with tiny bits of fabric.
