Here is a Vellum Pocket Card made from the vellum paper and other products from the Floral Romance Suite. I taught this at my class last month.
The Floral Romance Suite featured in the Occasions Catalogue and is unfortunately no longer available, but once you know how to make it, you can use this style of card with another patterned vellum, cardstock or Designer Series Paper. You can also decorate the front of the card however you wish.
The Scalloped Lace Trim tied around the pocket card is actually from the 2019-2020 Annual Catalogue, so it is currently available.
This card was inspired by a creation I saw by Chris Slogar. She is from America and as our card sizes are different, I converted this to make it a standard card for the South Pacific. I also added my own style of decoration to the front of the card.
If you would like to know how to make this card, I have a written tutorial and/or video available for purchase.
I hope this pocket vellum card inspires you.
