Isn't it great when the bit you are going to discard turns out to be the most interesting? I was doing some lino cutting yesterday of a bird and couldn't decide at first if I wanted just the bird or a box around it. Having left the box I did decide I preferred the bird on its own and cut of the extra bits, one of which was a triangle. And that's the bit that has become more interesting and playful.
Here's the bird, a lovely little thing in itself, standing 4cm tall.
And here's a card I made with the triangle off-cut that was going to be thrown away. Very happy with these!
