I found a template quite by accident on Flickr here and it is a freebie. All I had to do was link up anything I made with it, so I did.
It is quite easy to have a template, because you can quickly place your squares and glue them down.
I think I am a bit obsessive in not throwing away something that could contribute to a craft project, that in turn can be turned into a blessing. I love using up the scraps this way!
