Now, fold your bias tape over to the back side, encasing the raw edge. Pin as you go. Bias tape folded over to the back side: This is what my pinning looks like. I slip the pins under the bias tape on the top side and make sure it catches the bias on the back.
Baking Powder. Baking powder on the other hand, is actually a combination of baking soda plus another acid, in the presence of an inert stabilizer (a fancy term for an inactive ingredient that keeps the mixture from reacting), which is often a bit of cornstarch.
You can substitute baking soda for baking powder, if you increase the amount of acidic ingredients in the recipe to offset the baking soda. Youâll also need much less baking soda as it is 3 times as powerful as baking powder. Youâll need about a teaspoon of vinegar or lemon juice for every 1/2 teaspoon of baking soda.
