As I have noticed a lot of shops only offering a few sizes, here's a graph with my sales per sizes, to help you out. As you can see you will sell all sizes, some more than others, but you know, a sale is a sale. And since most sizes are cross compatible the effort to resize them can be minimised. The graph is over a period of 1,5 years. So take advantage of the large size portfolio which PrintShrimp is offering and get them up in your shops.
