I've finally got some time on my hand to start experimenting with cyanotypes but my main worry is exposing them. I don't have a UV light source (this is how i always exposed them while at uni) and I don't really have any money to buy one.

Now bearing in mind I'm in England and it's summer, do i need bright sunshine to expose them that way, or will 'average' daylight be sufficient? I don't particularly want to sit around waiting for the day the sun finally decides to show its face, or is that what I'm stuck doing?
