This is a great challenge, made me dig into my vellum paper that has been in retirement. Have solid color and pattern paper as well.
I have uploaded one card, and have another to get ready to upload and the third one in mind to make. I think I will be doing more cards with the vellum, as I have quite a bit.
Actually used an embellishment on the uploaded card that has been around almost since I started making cards.
Thanks for the challenge.
