When you think you’ve seen it all, you haven’t. Canada’s Post Office is celebrating both Canada Day and the 50th anniversary of our flag, by issuing its first stamp made from rayon fabric. Measuring 9 x 14 centimetres, the $5 stamp can be used for regular postage, but it’s really aimed at collectors. Stamp designer KOSTA TSETSEKA on the challenge of printing the large flag stamp: “There’s a real coarseness to the material, so ink doesn’t quite behave the way that we’re used to.” A lot of trial and error took place before the final process for creating the stamp was worked out, he said. Only 300,000 are for sale.
