I know there are at least a couple ways to get a quilted look on fondant, but as this is for a friend's wedding and I have 2 toddlers that will be around the house while I make this, I'd like suggestions for the easiest way to get the best looking quilted design. I saw a few that looked like they might work, but what is your favorite/preferred way to achieve a quilt stitch look on round tiers? I'll be using Satin Ice fondant if that makes any difference.
Is there a tool you absolutely love? I have 2-3 weeks to order/receive the tool. Thanks in advance!

If you are talking about getting stitch marks in your fondant, then I like PME's quilting tool. It has a tiny wheel on one end, and a dresden/veiner type other end.

If you are talking about an easy way to get the uniform grid imprinted, I'd use an impression mat. There are several available in various sizes, and they aren't that expensive.

I recently did my first quilted cake and I ending up buying three different tools...an impression mat which I found isn't any good on fondant because you have to press too hard, a plastic quilting tool that was difficult to use and finally a metal quilting tool that has three diamonds up and down. You can get them from "Creative Cutters" located in Richmond Hill, Ontario (they ship to the states) and they come in different sizes depending on the size of your cake.

For this cake, I used an impression mat just to get a vague line to go by. Then, I used the Wilton Cutter Embosser tool (~$5) to deepen the line.
