I am a big fan of these Martha Stewart clear stamps that you can arrange how you like on blank acrylic blocks.
I used them to make gift tags.
This year's designs included some acorns which matched my Christmas theme "nuts".
I used the huge Christmas tree with some other stamps to decorate our gifts.
I even used some of them to stamp the back of our Christmas card envelopes...
... because they matched the motif on my Martha cards from the Kodak Gallery.
