Hello :) I bought the Slimline Sunshine - Sunny Days Ahead die from Scrapbook.com a little while ago and couldn't wait to share some different ways of using it. I love to get value for money and I'm sure you do too!
This is my affiliate link to the die if you are interested
You can definitely use this on cards which are not slimline, simply by cutting and using parts of it. You can cut 2 from different card/paper and use the "waste" from one to fill in the other and you can also create a little stencil from it too.
You can see my video here -
I have used alcohol markers from Tonic Studios to colour the image and these are my affiliate links to these -
