Looks great Melissa! I don't know if you are familiar with Excel spreadsheets, but I found Excel quite helpful when planning the pattern for my first ever quilt - a baby quilt in pastel squares. I'm sure there are other proper quilting softwares that do this in a more sophisticated way, but this worked for me. You can colour the squares to get an idea of how the pattern will look, and cut and paste the squares to play around with the colours in different orders and configurations. I also numbered the colours in the pattern so I would know how many squares of each colour I would need. I have attached my spreadsheet so you can see what I'm talking about.
I'm sure I'm not the first person to use Excel for this? I'm such a newbie, :) I'm thinking - hey, what a great idea I came up with - but am probably way behind the rest of the experienced quilters here! :-)
