The first one is made by Rooike1 (Jeanet), a very talented woman who's become a very dear Zentangle friend of mine. It's called "A bit of spring".
The second ZT is made by Kraai65, a woman with many talents as you can see on her Flickr Photostream. This one is called "Lente (Spring)".
This third one is from Sandra van der Geest, a "newbie" amongst the Zentanglers. She just wanted to give it a try once and participated with the following ZT, which I think is gorgeous. More ZTs by Sandra's hand to follow...
Fourth in line... Mariet Dronten, please do have a look at her Flickr Photostream. Besides her ZTs she makes extraordinary and beautiful drawings. I think she's a very talented and creative artist. Enjoy her art!
The fifth, spring inspired ZT made by Dinie54, also a "newbie" amongst the Zentanglers. Famous for her gorgeous ATCs, which I really admire.
And last, but surely not the least, a ZT from Yvonne's ATC . A newbie as well on Zentangles. I "met" Yvonne on the SA (Scrappersanonimous)-forum and since then I'm a real fan of her art! She makes gorgeous and extraordinary ATCs, I think she's a stamp-goddess! :-)
Thank you all my dear Zentangle friends for sharing your amazing ZTs with all of us all over the world.
