Hi Ann, I did a bit of tambour embroidery including bead work years ago and still have the hooks etc. We had the tiny pearls threaded on a thread which we laid on the top surface then hooked the other thread from the back. Regards Nola
I saw your comment and answered yesterday but I was quite stupid and answered below my own photo!
So, I deleted my first message that was the following:
Point de Beauvais is a simple chain stitch but it is not done with a needle fortunately but with a tambour hook. I found a video (with comment in french!) in which you can see how it is done. It is here. For just having a look to the stitch, it is after 7min and 40 s, just before she set up a frame which can be interesting too!
Don't hesitate to contact me if you have any question or comment!
