This is the best I could get the photo to look as mirror card is hard to photograph. You can see some of the shine though, so you can see it's mirror card. I did mat the sentiment onto the same mirror card as the embossing was done on, however you can't make it out that well!
I am pleased with the result as I challenged myself to use something different to what I would usually do - use mirror card. I was inspired to do so from catching C&C the other day. The Spellbinders lady: Kim Hupke did it with an embossing folder and it made the mirror card look stunning by sanding the emboss revealing the white underneath. It makes such a difference as to my taste mirror card is a bit intense but for me this technique really worked.
Here's what I used from Crafter's Companion:
Vintage Christmas Collection A4 Embossing Folder - Softly Falling (Background embossing)
Sheena Douglass 5” x 7” Festive Embossing Folders - Ornamental Snowflakes (Foreground embossing)
Ebosser (To emboss my folders and cut the snowflakes. Crafter's Companion don't have it in stock at the moment though)
Coredinations Sand It Gadget Tool and Coredinations Dust Buddy - cleaning cloth (To sand off the top of the mirror card and then wipe up the mess!)
Spray and Sparkle Pearl Diamond Glitter Varnish (To spray the snowflakes)
Vintage Christmas Collection A6 Sentimentals Rubber Stamp Set - Let It Snow (Let It Snow sentiment Stamp)
Sheena Douglass White Stamping Card A4 - Pack of 60 (I stamped the sentiment on this and also cut the snowflakes from it.)
Darice Embossing Powder - Silver (To heat emboss the sentiment)
Collall TACKY GLUE 100ml - Quick drying glue (To stick the pearls on the snowflakes)
Collall ALL-PURPOSE GLUE - 100ml (To glue my mats and layers)
In addition I used blue mirror card, silver matt card, white pearls in 3mm and 4mm sizes and Spellbinders Cut, Fold and Tuck Snowflakes.
Sanding the embossed snowflakes after embossing the mirror card is not difficult. You just have to go lightly to start with. Make sure you are working on a flat surface - not over the edge of your mat - and hold the card flat/. Use the block in a circular motion and you should be fine.
I hope you all like what I've made. Thanks for stopping by!
