There are these sort of heraldic ones, which I don't think I will be trying to reproduce. Not that I don't like them, but they are a bit complicated and I am not sure what I would do with them.
Then there are the geometric ones, which can be reproduced fairly easily with a pair of compasses and a ruler. I have tried out several of these and will probably do more.
Yesterday's effort is one of them - and it was great fun to try out and play around with.
I tried tiling this one in a design programme but the computer appears to have eaten it - or saved it somewhere I didn't intend!
This combination of the positive and negative shapes is more interesting anyway and one of my tiling attempts did get saved where I wanted it.
A lovely Art Deco feel to this one. Not sure how I would embroider it - perhaps more of a background?
Thanks to Jackie for her suggestions on getting Blogger to behave. It still won't let me put gaps everywhere I want them - but it's better.
P.S. - I go away, eat my supper [excellent veggie chilli made by Wensleydale] - and the spaces have miraculously appeared!
