Full disclosure this is an Easter Blog Hop – but this card is not an Easter Card. I guess you could tie it to Easter because it has Chickens in it and Easter has Chicks – but that is really reaching!
I am a hobby demonstrator so the instructions and images may not be as good as other but I hope you like this.
I cased this card from an an amazing paper artist Tanu Creative you can watch her video here https://youtu.be/gWo0jBCmRLQ. I created the PDF with the measurements so between watching her video and using my PDF you should have everything you need to case the card too (should you want to)
