I have made a card too Inkodos April Challenge with masks and stamps.
The stamp that I've use are all from Inkido. The one in the center is a congratulation-stamp. I've made this for a friend how got 50 this week-end. I´m a bit surprised, because all my friends looks much younger ;-)
The masking is made with a sponge, water and acryl color and a second hand mask. The water make the softness of the color that I want to have. The flowers and the papers are also from Inkido.
The border- punch and leaf-punch are both from Tonic Studio.
Have a nice evening
