Designer Notes

150 Square is a lovely, square shaped envelope that’s a little different to the standard sizes you see every day, it’s designed to fit a 140 Square card comfortably inside. Our envelopes are made in Australia, they feature a stylish, v-shaped flap and are gummed so that they seal easily once moistened slightly.

The paper used to make these envelopes is matte and manufactured from 100% recycled fibres. It has a light, naturally textured finish and at 120gsm it is relatively thick for paper and it feels just lovely in your hands.

Kaleidoscope Sky Blue is a light and bright blue, it is available in card, paper and envelopes in a range of different sizes to suit the needs of your project. There are lots of blues in our ranges, so for a lighter blue, try Riviera Morning Blue or Confetti Blue Sky, for a darker colour have a look at Kaleidoscope Atlantic, Kaleidoscope Royal Blue, Kaleidoscope Sapphire or Riviera Midnight Blue and for a dark teal, try Riviera Stormy Sea.

The wide range of vibrant colours in the Kaleidoscope range is sure to inspire your creativity and spark plenty of new ideas for cards, scrapbooking, invitations, menus and many other projects. The card and paper are compatible with both laser and inkjet printers and suitable for embossing, varnishing and other treatments, but we always advise testing first.
