These are fun because you get six different patterns in one pack, but if you want to create patterns on larger pieces of paper like 12x12 I would probably recommend to get a ruler instead. I don't know what they're called in English, but I have some metal rulers with patterns on the side that you can align on your 12"-paper and then just rip it against the ruler to create the pattern.
So, for smaller items like cards or so, these are fun! But on bigger items, like 12"-layouts I would recommend one of those ruler-thingys instead since they are easier to use on bigger things and also works faster since you won't have to align more than one time before you rip.
They cut paper okay, but I was wanting a better quality to cut borders on a variety of material. They are plastic and better suited for kids.
If you've heard that paper edgers are "old school" or “outdated” don’t believe it. They have been around for quite a few years and the reason is because they really do help you scrap faster and creatively. My favorites in this set are the scallop, deckle and pinking - they make great mats and borders and are timeless. The deckle edge resembles the irregular edges of some vintage photographs and looks great on vintage photo MATS. Word to the wise: don't compromise the integrity of your photos by cropping them with these and other decorative paper edgers. Save the cute cuts for mats, strips and borders. You're layouts will look more professional and classy when you do.
I have some fiskars deco edge scissors and some from another company and I do prefer my fiskars to the others. They are a tad more expensive but worht it in my opinion. You get a cleaner cut with these, the handles are more comfortable which makes for better cutting, and the guides for cutting a straight line are easier to follow. If you're still into deco edged scissors I reccomend fiskars over ***** *****. :P
