Boy's Nonsense Quilt Block
Finished Sizes: 9" × 9" and 12" × 12"
Sometimes the simplest blocks become timeless classics. Boy's Nonsense has been around for generations, and it's easy to see why. With just a few pieces, it creates a bold geometric design that works beautifully in both traditional and modern quilts.
This free pattern includes both 9-inch and 12-inch finished sizes, so you can easily use it in quilts, table runners, wall hangings, or samplers.
Why I Chose This Block
I love classic quilt blocks that look more complicated than they really are. Boy's Nonsense is one of those designs. Although the block uses only a few units, the strong diagonal lines create movement and make the center square stand out beautifully. It's also a wonderful block for showing off a favorite focal fabric in the center.
This version uses the traditional construction method by sewing triangles directly onto the units. That means you'll be sewing along bias edges, making it a great opportunity to practice accurate piecing and careful pressing.
Later, I'll also share a scrappy version using my Y Block (¼-square triangle block) method, which gives the same classic look with a completely different construction approach.
Skill Level
Confident Beginner / Intermediate
You'll be comfortable with this block if you already know how to:
-
Sew an accurate ¼" seam allowance
-
Handle bias edges without stretching
-
Trim and square up units accurately
The construction itself is straightforward, but because several pieces have bias edges, a little extra care will help keep everything square.
Fabric Recommendations
This block works well with almost any style of fabric.
Some ideas:
-
Scrappy quilts
Using a lighter center fabric creates a nice focal point, while darker outer units emphasize the diamond shape.
Construction Tips
Because the triangles are sewn to patches, you'll be working with bias edges.
-
Avoid pulling or stretching the fabric while sewing.
-
Press gently instead of ironing back and forth to help the block stay square.
-
Starch before cutting if your fabric.
-
Measure after each unit so small errors don't build up across the block.
-
I've included an oversized cutting option. If you're unsure about your accuracy, cut the pieces slightly larger and trim them to size later.
