Boy's Nonsense
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.
Your support helps me create more free quilt patterns and tutorials.
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.
