This is my Bobbles Picnic Quilt, currently featured in the August issue of Popular Patchwork.
I love jumbo pompoms (these ones are 20mm, available from Frumble Fabrics).
This pattern starts off with 36 x 10" squares, so you could easily use a layer cake here.
I've quilted the quilt with a calico backing first, then added the pompom trim and a water resistant back (washable shower curtain) using the 'bagging out' method. A few extra stitches in the centre of the blocks keeps all the layers neatly together.
I'm keeping my fingers crossed that we get lots more 'blue sky' days so I can christen my picnic quilt!
