It's like baking brownies.
Make sure you have all the tools necessary: recipe, ingredients, pan, spoon, knife to cut nuts, measuring spoons and cups, etc = pattern, fabric [I always buy extra just in case] rotary mat and cutter, rulers, sewing machine & bobbins/or hand work supplies, pins, needles, thread, marking pens, and any organizing items you might need.
You can do it ... just as easy as making brownies ... just takes a bit longer and doesn't add calories.
