I make mailing address labels too, usually just plain ones but I saw this label in the Silhouette store and said -HEY, that looks like an address label....HA HA HA
I assembled it (no cut) and did an offset (cut) then shrunk it down to 3.815" w x 3.040" h
HA HA HA!! isn't it CUTE!!!! this is a sample..the others I printed out had family/friends address printed.
I'm looking thru the whole Silhouette store looking for more "address labels"...
