I made my first batch of cookies last week...I rolled out my dough using two pieces of pre-cut parchment paper from the kitchengifts.com and an accu-roller(has rings on each end for perfect layers- purchased at kichengifts)
I must say, I love the pre-cut sheets! They're a perfect fit for my cookie sheets. They gave me some for free and I loved them so much, I went back to order 100 more sheets! I tried the parchement paper off a roll and it was too wide, didn't fit my cookie sheets, and kept getting caught in my rolling pin. If you go to their site, they have several video clips giving you pointers. I love that store!!!!
