This fabric collection is 'Sun Print' by Alison Glass for Andover and is widely available now. What I love about this text print is that it comes in a variety of colours and not just black on white. There is also one print that has white text on white text. I saw this the last time on Annie's Seed Catalogue from Lake House Dry Goods. Oddly enough I bought this particular print by accident and at the time really did not know what to do with it. But since then I have used it liberally in my low volume projects (here ) as an alternative to a solid and that print actually has become one of my most precious ones. (You can see the print I am talking about in this link but it is not available anymore and the post written about it in the link is regarding fabric dying).
Alison's collection feature many other great prints that are ideal stash builder. You can see the whole collection on Alison's blog here
The fabric will be available here in the UK at the Village Haberdashery soon. On-line it is available in many shops in the US such as Hawthorn Threads, Pink Castle Fabric, fabricworm etc.
