Believe it or not but the product known today as "Crisco" (the name is derived from "crystallized cottonseed oil") was developed in 1911 by Procter & Gamble to replace the expensive animal fats used back then to make candles!
It was the first shortening to be made entirely from vegetable oil. But because electricity soon began to replace candle light and because the product resembled lard, Procter & Gamble started selling it as... food.
Because of its chemical structure, paraffin expands when heated and contracts when is cools off. This can be a good or a bad thing, depending on how you look at it: the contracting part greatly helps when the time has come to remove a candle from a mold but it's not welcome in the case of container candles where you want the wax to stick to the glass container.
Also because of its chemical structure, vegetable shortening like Crisco does NOT expand/contract according to its temperature. The logical conclusion is that, by mixing equal amounts of paraffin and shortening, you will end up with a mixture that will be 50% less prone to expansion/contraction than straight paraffin.
If you don't have access to special container blends, or if you're a die-hard do-it-yourself'er, you can mix your own container wax by incorporating Crisco (or any other vegetable shortening) into your formula.
The exact proportions depend on several factors: the type of base paraffin, the shortening itself, the other additives you may use... You will more than probably have to test and test again before you find a formula you really like. But if you want a kick start, visit the page about container candles formulas, your will find a starting point for your research.
In small proportions, Crisco gives a nice creamy look to your candles, even pillars or votives.

AN update for you. I have found that a tightly rolled piece of paper makes the best wick for shortening candles

Leah,
It should work just fine. I burned a lot of old bacon grease recently, it was too old to use for cooking but it burned just great with the candles.
