Crocheted "frisbee-like" disc

My friend, Pat, called me today and asked if I was interested in making a crocheted "frisbee-like" thing for her husband's co-worker.  I had never heard of them but a Google search of "crocheted frisbee"  gave me a good idea of what he was looking for.  Since I'm sick today and watching my British dramas, something to crochet was a good distraction.

I came up with this: 

 

It flies straight and for quite a long distance.  I was throwing it in the house so I don't know exactly how far it could have gone. 

Crochet hook size I
Worsted weight cotton yarn held double throughout.  Make color changes as desired.

Rd 1: Using magic loop method, make 6 sc in loop.  Join with sl st in 1st sc, ch 1 and pull closed.
Rd 2: Work 2 sc in each sc around.  Join with sl st in 1st sc, ch 1.
Rd 3: *Work 2 sc in next st then 1 sc* around.  Join with sl st in 1st sc, ch 1.
Rd 4: *Work 2 sc in next st then 1 sc, 1 sc* around.  Join with sl st in 1st sc, ch 1.
Rds 5-9: *Work 2 sc in next st then 1sc, 1sc, 1sc* around.  Join with sl st in 1st sc, ch 1.
Rds 10-11: *Work 2sc tog in next st then 1sc, 1sc, 1sc* around.  Join with sl st in 1st sc, ch 1.
The decreases in these last two rounds create the lip of the disc.  Fasten off and sew in ends.  Done!  Go fly a disc!  Beware, you can't make just one!
