I have been threatening this for a while. I cried D0-Over on my Threadless store. Retired 10 designs and remade 5 designs. I reckon they all look a ruddy lot better. The cloud one in particular I just resized and it seemed to make a world of difference.
While I was at it I found the custom store cover page and redid the artwork on display for each one and added most 20+ more colour options for each outside of just white. A shuffle of the designs and a new store layout added too. Will be working on little promo banners for each next.
Some of the retired designs will be back once they have been redrawn. For now, I am pretty darned happy with the new store look and shirts.
