The following are hornbooks from Bunny and Apryl. All would work as framed pieces too.
From Every Mountainside was worked on Vintage 40 c Sea Storm.
Sweet Liberty was worked on Vintage 40 c Fawn.
Primer Hornbook was worked on Vintage 40 c Meadow Rue. The first printing of the chart doesn't say vintage but we have confirmed that is what was used.

Thank you Bunny and Apryl!
