Hi! I believe the kit comes with a premade hole at the top, so when you pour the resin you will automatically have a hole. I am awful at guestimating how many it makes, because it’s been a minute since I’ve done this, so I can not answer the second question. I know enough to always have two kids on hand though, because they do go quickly when making multiples of something. Hope this helps!

I have two questions–forgive me if you answered these in the article and I just didn’t see them:

1. When (at what stage of the process) and how do you make the hole in the bookmarks that you later put the jump rings through?

2. How many bookmarks would you estimate one resin kit makes?

Thanks!
