Well I have finally started after doing lots of research and receving some much need advice.
I decided I would order papers from Lizard of Oz only to find that when they arrived, they were printed onto a sheet and I had to cut them all out! I'm too lazy for that but the instructions that came with them were very informative.
I covered some papers and then decided I would join them together - that is when all the fun started. I found it nearly impossible to keep them all straight and in line and dreaded to think how I was going to attach the following rows.
Jean from Linen & Raspberry has been working on her own clamshell quilt that she had done in a class with Brigitte Giblin and I have been admiring her progress for some time. In a recent post, she mentioned that Brigitte Giblin has a new website and you can buy her patterns and download them as soon as you have paid for them, so that is what I did.
Brigitte's method doesn't use papers at all and is different to everything I had previously read. Unfortunately I can't do a tutorial on it because it is directly from her pattern, but if you are interested, I found her website to be great. The pattern was very reasonably priced and the download worked like a charm. If you click on her name above, it will take you to her website.
