More Mix & Match and Swirls

I am impressed with the ideas given by my customers... I pun tak terfikir nak buat cam tu.. The blue one is from Shikin to her brother.. and she requested the symbol pi.. and I told her that I no longer have my math books.. please refresh my memory wrt the symbol.. :-p (sungguh teruk!) and another one was designed by Bayani... Thanks dears!
