Val in England sent me this great tip:
I recently read an article explaining how to make a beading chart using a spreadsheet on a computer. I found this excessive! As a miniaturist I have for years drawn out all my designs for petit point carpets on ordinary graph paper colouring the squares for the design.
I now do this for my beading designs, quick, easy, cheap, and easy to alter. It is also great for all those who are computer illiterate!!
