I have been using Excel and Paint since I started quilt making, its a bit fiddly to start with, but you soon get used to it and good way to get an idea of how colours, patterns etc. go together, if like me you can't afford EQ or other programs. Will save your tute to read later, but it looks very good. I'm never very good at explaining things, its great that you can pass this on to others. Its fun too. Thanks
