I have just finished my examples with the challenge YOU Kit available at Scrapping Outback
Here is a stamped image that I coloured in with watercolour pencils and then lots of Clear Embossing Powder....Here is what I did to get the Broken Glass look ..
Firstly stamp your image and colour in .My stamp is from Impressive Stamps Australia
Then apply Clear Embossing powder over the top heat with a heat gun I have applied
5 Coats.Please be very careful when embossing I have a lovely little burn on my finger..
After you have done your last coat and you are happy with the depth place your piece in the freezer leave it in there for about 10 mins .
After you have removed it from the freezer take your piece and bend it until it cracks.
That is it you are now done..Enjoy I hope you like this is not my technique I am sure it has been around for years but it is really cool.
