I really don't want to discourage you but as a beginning quilter myself ( I have sewn clothing and other craft items like bolls, bags etc for 40 years) I would say start with something easier as your first quilt. Maybe half square triangles or something like that. You'll learn about 1/4 seams, squaring up, matching seams but not with something as difficult as an isisecles triangle. Then when you feel more confident, tackle that quilt.
