Unles it's a tiny bookmark, they probably won't be long enough as an 18" length only gives you 9" per bobbin. At a usage rate of 2 to 3 times the length of the lace, that gives you 3" to 4 1/2" of lace, IF you don't have any workers, and if you work right to the very end of the thread. As Jo said, you can add leashes so you can do this.
You'd get more options if you start and end with a tassel, as then you can have a bobbin per thread, and will only 'waste' say 4" for the starting tassel and anchoring the threads. You'd have enough thread for 18 pairs wound in that way. Why don't you work a simple all ground book mark, with a point and a tassel top and bottom. That way you'd know how far the thread will go. Once you know that, you can design a bookmark with spiders, grounds, rose grounds etc, but avoid designs with cloth stitch areas. Narrow half stitch trails would probably be OK, so long as you DON'T do an extra twist as you go around the pin, as then you'll use a different worker every row. What I am more worried about though is if this is a silky rayon thread, it is often difficult to get it to tie a firm knot. This would make it difficult to finish off the tassel - you may find you need to use a matching cotton thread to do the final knot around, and even then you may find that the ends slip. I used a rayon thread of about this thickness as a gimp with cotton as the main thread and the ends just kept slipping out of place. So do experiment before you spend the time doing lace.
