I have taught a few people to quilt. It’s super easy to be lax by choosing a pattern that has all squares and rectangles for a first project. I did this with my niece thinking it won’t matter if she didn’t hit a 1/4” seam. She was doing a square framed designed. Easy right? Wrong! She started in making blocks and I was dumbfounded by the irregularity of the blocks. So I will be squaring up the blocks. Time to work on the quarter inch seam. The other side of this is eventually your student will be making quilts on their own and they will try to tackle something with half square triangles and nothing will line up at all. So take my advice start with the ¼” seam. Work on that first. Invest in the ¼” foot. Time well spent.
