It's possible - but not very likely - that this girl is a big arts and craft lover, and she just loves spending her time putting collages together. Maybe she's really good at choosing the right pictures to blend together on a wall, or she's skilled with different patterns and materials. We think that's unlikely, though. We suspect that this is just a case of having a spelling mistake on a t-shirt - and quite an ironic one at that - and not noticing.
If the intended message of the t-shirt is to say that she loves college, she may want to get back there and spend a little bit more time in English class. Who's the bigger fool though - her for wearing an obviously misspelled garment, or the person who made the t-shirt for not looking up the spelling before they put it on sale? We suppose it's her. After all, the seller has got her money now!
