"Fur-ocious Feline" "Monster Parade" & "Hello Kitty Halloween treat" invitation cards by Tiny*prints
Happy Halloween by Kristen Craft (this one is not available for buying anymore :C)
Some years ago I made invitations for my kids inspired on the Monsters Parade one, they ended up very well! I still have to think about which invitations I'll give this year for my kids's party (ok, it's kinda late, but still, I'll try to think about something this weekend ;_;).
Have a nice day~!
