Many Thanks for all the kind words...

The sheet was as you saw,,,with more time I will be making it taught as I now know it works and also how to do it,,,

So yes I did find the creases would and did need sorting, they don't chroma well... I'll iron the cloth first as well.

And as for the colour,,,I went into a material shop and looked at a green colour I liked and thought might work for £4.50
