I designed a special wish/blessing/gift card.
There is a rose on the front of the envelope; and when you place the stem of the flower into the down left corner of the envelope where there is a gap, mimic the process of "putting the stem and root into the pot/mud " then the rose will light up, lighting up the wishing message written on the top right: "To Some Special".
Measure the paper and draw the lines for constructing an envelope;
Creating the red rose pedal;
Dig a hole on the envelop and the pedal where one of the wire (stem) will go through to connect to the battery inside of the envelop;
Put the battery;
Close the envelop;
Write your wishes above the petal of the rose;
