This thread has been really helpful - I'm hoping it's to too late to get some more advice on this topic. In the Bouchon Bakery cookbook they advise: "Professional confectionery rulers can be very costly, so we use plastic ones that are cut 22 inches long by 1/4 or 1/2 inch square. Plastic fabricators (such as Tap Plastics) are a great source for buying inexpensive food-safe plastic guides cut to your specifications." They also recommend taping confectionery rulers to the work surface to prevent shifting. Has anyone purchased plastic bars like this? I looked at the Tap Plastics website http://www.tapplastics.com but wasn't sure what type of plastic is food-safe and best for this application - thought I'd check if anyone has already done this and can recommend the exact product they had cut to order? Thanks!
