Waxing Crescent Moon
Go to the web version of Palomino Dream <https://palominodream.blogspot.com> and look at the right sidebar. You will see where "Followers" are listed. Click on the box that says "Follow" and follow the directions. They are as simple as entering your email address. Then you're good to go. You will be notified whenever a new post comes along. Easy peasy!
Note: this is easier to do on a laptop or PC than a phone. If you are using your smartphone, you get a reduced version of the blog. Looking at the blog on your phone, scroll down to the bottom and click on View Web Version. Then you will see the whole shebang, including the right sidebar, which is what you need to make the change.
