I hve always had a hard time rolling out the sugar cookie dough to an even thickness. Do people use guides? if so, where can I get them? I have seen very thin guides for fondant but I need something thicker. Does anyone have any tricks they would share abut getting an even roll out?

Go to the hardware store and buy two wooden planks or dowels that are the right thickness for your dough (I'm suggesting approx 1/3" to 3/8" thick?) lay them on either side of your dough and roll it out until your rolling pin hits those on either side. (i.e. you won't be able to roll thinner than that because the wood stops you). A cheap solution.

There are also rings of different thicknesses that you can buy to put on the rolling pin itself. They do the same thing, preventing you from rolling out thinner than they are.

I've been using the rubber rings that go onto the rolling pin. You can get them in most craft stores and in some grocery stores. They come in different thicknesses to choose from.

Oh thank you so much! That's a really good idea about the dowel rods...I'm going to stop at the hardware store on the way home tonight. Thanks again!

I use the dowel method.
For those who use the rings: Do you just have a long, thin rectangle of dough?

I use the wilton wooden dowel rods.

So I stopped by my handy dandy hardware store last night and picked up three different diameters...cut them in half because my pieces were 48 inches in length. WORKED LIKE A CHARM!!!! Thank you so much..I've struggled with this issue for so long and so appreciate the advice and simple solution!!
