I also forgot - there is a good manufacturer of promotional products for churches and so on - they do mugs and pens and baby aardvarks and badges and bookmarkers and so on with your text on and they also do embroidered badges.

By the way, I may produce some t-shirts for my shop in a while ... anyone have any image/text ideas?
All I have at the moment is the old
"I walked 700 kms doing this pilgrimage and all they gave me was this lousy t-shirt" ...
(no, of course it's not true about the aardvarks)
