Drafting A Quilt Pattern and /or Quilt Block

It’s Monday and time to get out your pencil and 1/4″ graph paper. Please mark this post if you think you might want to refer to it in the future – I’m not going to work this hard on drafting again – ha!

1. A 1/4″ square represents 1″. After adding the 1/4″ seam allowance all the way around, your square would be cut 1-1/2″ x 1-1/2″. The 1-1/2″ square would finish at 1″.

A four inch finished square would be drawn as 4 squares on the graph paper and would be cut as 4-1/2″ x 4-1/2″.

2. An additional 7/8″ is added to any cut measurement if you want a triangle square. To end up with a 2″ triangle square, cut your square 2-7/8″ x 2-7/8″ and cut it once diagonally. When two of these triangles are sewn together, the finished size will be 2″ x 2″.

3. If you want a quarter triangle block, add 1-1/4″ to finished size. For a 3″ finished quarter triangle block, cut a square 4-1/4″ x 4-1/4″ and cut it twice diagonally. The straight grain of the square will be on the outside edge of the triangle to avoid stretching.

When sewing these 4 quarter triangles together, the finished size will be 3″ x 3″.

NOTE – when I say Finished Size I mean the size after being sewn into the quilt – not with the raw edges measured.

These are your basic measurements. Now let’s tackle Connie’s table quilt in the next post – in case this one disappears!

        You ARe my “quilting sister”, Mary – I too flunked algebra and declined geometry, and have regretted that since my first quilting stitch! These measurements would make so much more sense w/ a little geometry background. Thank you so much for making sense of it.

    Thanks for taking the time to show us some fundamental drafting. I am putting it in my “tips and tricks” notebook. A handy reference tool.

    Thank you for the good notes. I feel the same way as you do about math. Too bad we weren’t in the same class- we could have helped each other! It’s snowing again in Wisconsin. I think we are to have snow most days this week. Good news-my husband is getting out of hospital rehab tomorrow. He’ll continue rehab at a center near us. Hope you are having a good day.
