The Rolling Seam Presser is a handy tool that will save you time because you can temporarily press your seams open enough so you can keep sewing or quilting instead of having to get up and go to your iron and pressing mat repeatedly. You'll also save your fingernails as you won't have to use them as a makeshift press. When you do go to your pressing mat, the wood roller can be used as a mini clapper when you need to set small seams. In addition to being used for sewing and quilting (including paper piecing), the rolling seam press can be used in paper crafting, scrapbooking and more! The Rolling Seam Presser (RSP) is made of a lightweight plastic with a wood roller. This makes it easy to toss it in your sewing or project bag when you want to use it on the go instead of lugging along your iron or other tools. Let this neat little tool help you make more of your valuable quilting/sewing/crafting time by letting you stay at your sewing machine or workstation.
