I assumed a OSW was using a 12x12 sheet but on further investigation it looked like most templates out there are using an A4 sheet which was a bit of an annoyance as I had already decorated my 12x12! So my efforts evolved as time passed and I will have to do a retrospective template for this - so bear/bare (never know which one it is!) with me!
Anyway, I started with a Whisper White 12x12 sheet and randomly stamped it with Bud Basics, using Basic brown, River Rock, Pale Plum and Soft Sky inks.
When I do this next time I shall make sure I actually have a denser covering of the design as once it gets split up in to smaller pieces you get some pieces that really don't have much pattern on then so I found myself adding more stamping to a few of the pieces as I assembled the cards.
Not really knowing how to cut the sheet up I did it this way.
On the whole I used it pretty much as is but I did chop a few pieces down a little more. I shall really have to work out a template that I can easily repeat.
I have just sat and worked out a proper template, it is not perfect but it is good enough!
I have added the measurements (in metric) and numbered them and these correspond to the numbers of the cards in the slideshow below. There are a few little bits that are not numbered, which I did not use but obviously with a bit of creativity you could easily make another card from those, I was kind of over it at the time!
Now out of this template and 2 pieces each of A4 Soft Sky, Chocolate Chip, Whisper White, Pale Plum and River Rock I made 14 separate cards

However, if you do copy this template and post it on your website or publish it anyway please do not pass it off as your own work and if possible please link back to my site.
If you are using it at a workshop feel free to say you designed it, we can't have your guests thinking you are anything other than fantastic!!
