Inkspirational and it is to use small stamps.
I didn't find this easy at first and this design wasn't my first attempt. But I'm really pleased I persevered as I like what I made in the end. That's the nice thing about challenges - they can get you out of your comfort zone in a good way.
I used a set by Craftwork Cards that's got loads of tiny Christmas stamps. I made a heart stencil and stamped them through it in red and green. Then I very daringly (given how often I mess things up) stamped the (Avery Elle?) sentiments, leaving it a single-layer card.
