I made each one up as I went along, previous crochet experience and knowledge helped muchly here........
The white one turned into a beautiful medallion so I wrote down the pattern as I created so I could share it with you..........
Chain 6 and join into a ring with a slip stitch
12 single crochet into the middle of the ring and then slip stitch to first single crochet
2 single crochet into each stitch around and again join with a slip stitch to first single crochet (24sts)
*Chain 11, skip a stitch and single crochet into the next stitch* repeat all around and slip stitching into the bottom of the first chain.
Slip stitch your way up the side of the chain until the top of the 11ch loop, single crochet into the top of the chain loop, *chain 5, single crochet into the top of the next chain loop*, repeat around * and then slip stitch into first single crochet.
*Single crochet into middle of 5 chain loop 6 times*, repeat around * and then join with a slip stitch to start.Finish off.
