I have just acquired these seam guides.
The will either languish in the tool box for ever or be incredibly useful, but at £8 for both including postage I thought they were worth a punt.
The girl who makes them usually does templates for some of the bag making patterns I use and she also says she does FM quilting rulers, which was how I found the seam guides.
Nice to support a small business. [ You are not allowed to view attachments ]
