Doesn’t the picture above look like a crochet spermatozoom, perhaps carrying a tiny X chromosome? (And, yes, I did have to look up the singular form of ‘sperm’.)
Anyway, Val over at Yarni Gras! has this great tutorial for making marble-enclosed book thongs. Her Crocheted Bookmark calls for yarn and a size F hook. I like this supply list because not all crocheters have a plethora of steel hooks and crochet thread at their disposal.
I used Babysoft in bubblegum, a clear marble and a size C hook. With a much smaller hook than gauge, the decreases make lacy holes. You can see the upper half of my bookmark has some open work because of this.
I was surprised how fast this book thong worked up. With the tutorial pictures, the pattern is very easy to understand. If you’re looking for more bookmarks, Val also has an owl and a blowfish/peep pattern, too.
*That’s cool* a random fact
Virtually all the scripts of the unsuccessful sitcom “Hey, Landlord” (1966) were eventually rewritten as scripts for “Laverne & Shirley” (1976).
