so,first you eat all the chocholate,then cut out the places that has smooth surface(no dimples) and use an exacto knife(cutter) and tracing graph paper(calc) to make the required size (6.4 cm/8.9cm).that paper is just great.i found out the all my rulers had unproportioned centimeters !!!
for allowing a little writting at the back of your card as you have to sign it (title,date,signature eventually)use a bit of sand paper and scretch the area.i was very contented with the result...loved to see how those little clouds got personality :)
i studied a bit the wrapping papers inside and it is a bit more waxed,but still allowes marker and good for pencil as a regular atc card.
now the pictures that worth more than any words...
now, going further i am making card sleeves from heavy wrapping paper.it may not be very neat but it holds and protects the cards perfectly.it measures about 10 gramms :)
