The site is called ATC's for All and I would encourage you to take a look at their gallery even if you have no inclination for making ATC's as I am sure any papercrafter will gain inspiration and enjoy admiring these wonderful tiny pieces of art.
The above series of 3 ATC's was created for a Butterfly Themed Swap
They have been created using Dark Room Door Stamps, Distress Inks, Tria Markers, Glossy Accents, Gold Marvy Metallic Markers, Kindy Glitz.
The Butterfly ATC's above I have created for one of the swaps on the site and I have to make special mention of my friend Judi who gave me the inspiration for using the distress inks and Dark Room Door Leaves on these cards.
I am finding myself looking outside of the box for ideas to create backgrounds etc for this tiny creations and over the coming months I will no doubt be sharing more of my ATC creations with you.
