i did, mine was very simple. i bought white blank cards (one side matt one side gloss) 300gm per piece.. got it cut into 5 x 10 " ( n some other sizes) bought the thickest red marker n wrote on it. very very simple. thats for flashing words. for colours shapes i cut into 11 x 11" and then i use coloured papers, cut into triangles, squares etc n used a black marker to define the outline. did not laminate cos i think very expensive to laminate soo much..
fr papers you can get from hiap moh
