There is something else you can do to blend other than gamsol or baby oil. It works like a charm it's called Goo Gone. You don't need very much on a stmp since it doesn't dry as fast as gamsol and it isn't as oily as baby oil. It breaks down the wax in pencil crayons (Prismas, etc.) very nicely and allows you to blend. The nice part is that here in Canada it can be purchased at the Dollarama (a dollar store), not sure about dollar stores in the US. I know that stores like Michaels, Jo-Ann, Home Depot, Staples, Office Depot, etc. carry this product as well. The product was actually made to remove labels from store purchases on plastic, glass, etc.
