I forgot...

...to take plastic bags into the garage when I did this pour. Because what I have been doing is placing the plastic on top (the canvas/paper is only small). It was in a flower shape, but there wasn't enough time to go back into the bungalow and get them.

So I just got another piece of photo paper (I had done this one on photo paper to see how it would work), but first I had sprayed the second piece of paper with silicone spray.

If I'd had the plastic bag I could have kept the shape of the initial flower better, but I didn't so I put the second piece of photo paper on the first and obviously it squished outwards into a blob.

But I did get some cells!
