I'm glad you asked -was wondering how I'd managed to miss them! Thanks!
I was wondering the same as you. As for d just use b and turn it around. I couldn't also find e but will go back and check. I think I have a, but now you have me thinking I do not. Will check and if not they will be voted for. Happy stitching
Lower case d & e have not been offered. you can get a d by mirror imaging the b. For the e you'll need to purchase it.
