Here's how I did it:
The photos of the vintage ladies were upcycled from my bridal shower decorations. I placed them on blank cards from Michaels (rather innexpensive with a coupon) with glue tape and photo corners; super easy. Next I combined unmounted rubber stamps to my medium sized acrylic block to create the "Thank You" with a border.
I then started the heat embossing process. After dabbing the stamp on the ink pad I quickly stamped the card and sprinkled embossing powder over the design. Next I tapped off the remaining powder into my handy tray and exhaled a couple of strong breaths to make sure there was absolutely no stray embossing powder. Lastly I turned on my heat gun and miraculously watched the embossing powder turn solid!
This was my very first time heat embossing. I learned of this style craft from, can you imagine, a wedding blog. After watching a youtube video on the how-to's I decided to give it a try. I am really pleased with the outcome, however next time I will use clear embossing powder. No matter how hard I tried, I could not get rid of the leftover powder on the card and it ended up looking a little messy. I think some experimenting is in order but I am totally addicted!
