I wanted to make a few of these into large cushions/pillows. And so, I just continued some of the patterning for a much bigger mandala. These ones measure 50cm/20" in diameter. They are very big!
The backing for the cover is a plain one which just lets the magnificent mandala shine as the front of the cushion cover. I have a pattern for this backing which somewhat complements the mandala. The backing I created for the pillow fits a 20 inch cushion, but can be downsized to fit the regular sized Picots & Petals Mandala. I've mentioned in the pattern where you need to stop crocheting so that your backing fits the Picots & Petals Mandala which crochets up for me with a 4mm crochet hook and double knit yarn to 18cm/7".
