Linda would you really need the pattern? I hope this is the pattern you have in mind. I haven’t seen this panel but I want to get one too-thanks for telling about it.
Anyway, the pieces border around is just half square triangles, quarter sq triangles and hourglass . I took a picture to show you the blocks. You can see the four HST on the corners and you put it together like a 9 patch once you get your four QST, four HST and one Hourglass made.
Let me know if I can help but sorry, I don’t have the pattern for you. I will be making one though, so thank you!
