I am so glad it was helpful. I bought the stencil at a local fabric store many years ago. I would suggest asking the store clerk for help. If you cannot find it, you can make it yourself from a cardboard. I made my first stencil that way and I loved it. Please let me know if you were able to find the tool.

Thanks for the reply. I found something similar from Hemline (UK) but the one most like yours seems to be from Clover (here in the US) but not available on their website. It seems so helpful to have it in metal so it is not affected by steam or heat. I will keep searching. Thanks again
