To make a loom, you will need a canvas stretcher and some string and some precise measuring. You will to start from the same distance of each corner on each side. Your increments going down the short side should be equal-distant. They will show you where to place the nails you will tap into place alongside the framework of the stretcher. You will take your yarn and use the nails to wrap the yarn around and create your loom. This yarn pattern is called a warp and it gets tied off on the bottom nail. Take cardboard and weave it through the warp and push it to the top. Finally cover the nails at the bottom with painters tape.
