The Dots and Spots Die (#159164) is a versatile addition to your stamping supplies arsenal!
You can use the die to make a mask and using a blending brush through the mask make a polka dotted pattern on the card base as done in the first example.
I used Gorgeous Grape ink (#147099) and holding the paper mask in place with my left hand using circular motion with a blending brush (#153611) added ink to the mask to create the polka dot effect on the base for a fun, whimsical background. I added ink in a diagonal swath using the same blending brush and then fussy cut some of the irridescent snowflakes from the Snowflake Specialty Vellum paper. (#159832)
The sentiment is from the Perched in a Tree stamp set (#159791) in Gorgeous Grape ink.
