I am a Denusk Horse Kelvic so I could definitely do some threads with you, perhaps if three is too many Derailey wouldn't mind doing a three person thread.
At this time Jaye would would be less than 2 years old so she wouldn't be ride-able but could definitely teach you some things or participate in some ways.
You two just let me know what is going to happen. Derailey will be there.
