EXCELLENT CUTTING TOOL (especially if you read and follow directions)
Let me start by saying---when you buy a product, like these Clearly Perfect Slotted Trimmers by New Leaf Stitches--take the time to READ THE INSTRUCTIONS. After reading countless reviews that were complaining because they couldn't see their fabric through the paper (which the instruction inform you to REMOVE) I realized it wasn't the product, but the individuals that was the issue. I have scanned and shared the two sides of the clearly laid out information that comes with the two slotted trimmers. "REMOVE PAPER BACKING BEFORE BEGINNING." In the third picture, I have left the paper backing attached to the top one and removed from the bottom one--so you can see the difference. In the fourth picture you can see how the trimmer slots the ends, so when you open and press, you aren't then trimming off the dog ears. I have raved about this product at my local quilt shop--and yes they do carry them. I love that this product is Made in the USA.
