Thanks to blog searching (http://www.tatteristic25motifs.blogspot.com/) I found this great idea for a bookmark. This is Lizbeth size 20 thread in tropical punch. I'm hoping to make some more of these for some quick gifts. Of course I just had to check it out inside a book and the closest book was "Introduction to Mechanics of Solids". Isn't that your closest book? This is motif number 2.
