splityarn calls this the "Easiest Knitted Sweater Zipper Install Ever" and it looks like it might be. I haven't tried it yet but I'll let you know if I do - my one attempt to put a zipper into a knitted sweater came out OK, but not this nice.
This works great! Much better than the gelled version of DIY air freshner and easier to make. Everytime I walk in the room it smells fresh & has a nice scent to it. Will be doing in my whole house soon. -diy air freshener - baking soda and oil
