I decided to try my hand at converting a Tina Frauberger edging into a bookmark. This is Figure 28 from the 1919 publication of Schiffchenspitze, which can be accessed for free on Georgia Seitz's website for the Archive of Tatting Books in the Public Domain.
Here is my progress so far:
I'm tatting this in Lizbeth size 80 Scottish Thistle. It's coming out to be about the same size as the Priscilla bookmark in size 80. Size 40 would work too, but size 20 is a little too big for a bookmark.
I had the same experience as Frivole when tatting a Frauberger pattern. This one had to be significantly reduced in size from the original (I reworked the numbers from the ground up to make it easier to tat). The only counts that remain true to the original are the trefoils along the periphery of the bookmark. I will share my version of the pattern in a week or two (still thinking about making a minor edit to what I'm using above).
