I remember the day, many years ago when I discovered that homemade salad dressing takes about five minutes to make and tastes worlds better than most bottled versions. It was a revelation to me, having been raised to believe that Kraft invented the stuff and held the secret formula. It also taught me a lesson that seems to be reasserting itself regularly lately - there are no secret recipes any more. Thanks to the global community we live in there is little information that is not readily accessible. So, when I ran out of modeling paste this afternoon, instead of walking to the art store for a fresh supply I went to the computer instead. Sure enough someone had figured out what it was made of and darned if it isn't the very same thing that makes chalk paint - chalky (see early post "I love Annie Sloan"). Again, I don't know what the exact composition of say, Golden modeling paste but who cares? I discovered that I can make my own by adding calcium carbonate to mat gel and I can make it any consistency I want to suit the job at hand. Five minutes to luscious goodness. Too funny.
Because it is very porous, it can be used under wax also.
Why I never thought of making my own before now I don't know but I do know that I will be experimenting with DIY texture gels, fibre gels, bead gels...hmmm, I wonder what dog fur looks like in gel?
