1. The first thing you will need to do when making a Harry Potter house scarf is to select the appropriate house color. There are different types of house colors you can choose from, such as Ravenclaw, Hufflepuff, Slytherin, and Gryffindor.
2. Harry Potter house scarves can be made by sewing or knitting the material, but knitting seems to be an easier process, so we're going for it.
3. Choose a color and cast on 23 stitches.
4. You can use any pattern of stitches to Knit 20 rows. You can either garter stitch or stockinette stitch. With any of these two stitches, you will create a bumpy texture on one side, a knit texture on the other side.
5. Chance another color and knit 20 rows. You can use any of the two stitches offered above.
6. This stage is where you will be alternating the colors and knitting the two rows you have made in the previous steps.
7. The two stitches should be knitted to the tip of the needle, after which you remove the needle.
8. You will need to tie the yarn. Also, tie the ends of the scarf together and weave them in.
