When fabric shopping, border fabric is always on my list to buy and when I find something that looks interesting, it is bought and put away in my stash until that day when it is needed.
How do I know what to buy? I don't until that certain fabric comes into view and viola, that is when I know. Blues, reds and greens are the usual standard as my quilts are based around those colours.
Anyway, after much pulling of different fabrics, this is the choice for my borders. Oh look, blue, red and green. LOL Can't go wrong with those colours.

Have a great day!
