Stamping, masking, clear block stamping... this is a fun technique card
which is easy to create and looks pretty effective (in my opinion).
Clear
block stamping is a really fun technique; just ink up your block (you
can use ink pads or water-based markers), then spritz with water before
pressing onto your paper. Bizarrely, despite this being a faux
watercolour technique, it works best with Whisper White cardstock rather
than watercolour paper.
The shells are
masked using sticky notes so that the images don't overlap. The secret
here is to work from the front to the back, so you stamp the large shell
first, mask it, then stamp the images 'behind' it. Another top tip is
to retain your masks - keep them in the stamp box for future use, as
this will save you time when you revisit the technique.
