My boss was designing high end holiday cards when she discovered she was running out of specialty envelopes. As her assistant, it was my job to go out in the cold to buy envelopes uk. She needed translucent vellum envelopes, because her cards were designed to make a visual impact even before they were opened. I was amazed at the vast number of colors they came in, but the only colors I could get were red, kiwi, rose and violet. They were perfect for two sided translucent printing. The envelopes were environmentally friendly because they were acid and lignin free, and they were recyclable.
