Do you mind they will be the same (expect "Mario"'s face)? The sweater is either WHITE or ORANGE in colour, maybe you can check the size of Keon's one on 1031 party, and then ...
Now Keon's one is 6 in size, should I buy 8 for Him Him?
The tee + hot stamp paper is around $70 to $80, are you OK?
Since I've to choose a suitable photo and spend some time to cut out only the head part in the computer, are you mind that I'll make after 1031 birthday party?
