u forgot someones birthday?, wy not just print a birthday card. best results is using a textured pei sheet. printed upside down.
u can use a fineliner to write on your birthday card.
easy to fold
folded its 11x17cm
(i had to add a small white strip on the front left side of the card otherwise it would snap and break becease there wasnts much holding the card together, still looks good)
