Triangle Quilted Blanket for Baby

Quilt finished

I found a tutorial to make this “quilt” on SeeKateSew; she has some amazing baby DIY projects on her blog! I saw a picture on Pinterest of the baby girl’s quilt she made in this same design, and pinned it months ago when we first found out we were pregnant. I loved the colors she used, but they definitely wouldn’t match our baby boy’s nursery. After being a little intimidated at the thought of quilting and matching up corners/lines, etc. I finally took a closer look at her blog post. I was surprised to find out that she had designed a fabric on that already had the colorful triangles printed in this fun geometric design! In her tutorial, she has you “tracing” the triangle lines to give the impression of a quilt. I picked out the color scheme that matched our nursery the best and found a matching back at the local craft store and got to sewing. So here is my adaptation and experience with SeeKateSew’s one-hour triangle quilt.


First, I gathered supplies:

Quilt baste3

-2 yards of triangle fabric from SeeKateSew’s spoonflower page. You will have the option to choose what type of fabric you want; I chose the basic cotton ultra (it’s soft and seems to be durable)

-2 yards of backing to match (I chose another 100% cotton material)

-Batting. I chose Mountain Mist Cream Rose 100% Cotton Needled Batting, which I found at the local craft store. You can choose whatever you want, this one just had the perfect lightness and thickness for my taste. Make sure you check the dimensions before you buy!

-2 packages 1/2″ double fold bias tape (or make your own binding). I used Wright’s Brand from Joann Fabric Store in a soft grey color.

-Thread to match fabric

-Spray baste. This stuff is awesome! It’s like quilting spray glue; very easy to work with.

Triangle fabric

Step 1: Cutting

Lay the fabric flat and cut the length at 53.5″. The dimensions of the fabric to start out is 72″ X 42″ and the final project all said-and-done will end up being about 54″ X 42″, the perfect size for baby.

Cutting the length at 53.5″ should slice one column of triangles directly in half and give it a clean look.

Cut your backing to match these dimensions.

Step 2: Basting

**Make sure you have a large, hard working surface for this part otherwise you will end up with wrinkles in your fabric.

Lay the batting out flat and start spraying at one edge. Lay your triangle fabric on top, working with small sections at a time. Smooth out the fabric as you go, and continue down the batting until all of the triangle fabric is attached. The spray baste is easy to work with, and doesn’t dry right away so you can pick up the fabric and re-position as needed. Flip the entire project over and repeat the same basting method with the backing material and smooth out any wrinkles you have.

Step 3: Trimming

Trim any excess material you may have from the edges. If you’re a perfectionist like me, check for symmetry and the same amount of triangle showing on each of the four sides!

Step 4: Sewing the triangles

Basically, you need to sew over every line where the triangles meet. This is the most time-consuming part of the project, but it’s super simple! Just take your time and really pay attention to creating straight lines.





Quilt binding


Step 5: Pin the binding

Take the binding out of the package and unwrap the entire thing. Wrap the binding around both sides of the quilt and pin in the direction you will be sewing. The corners can be tricky; I googled a few different ways to finish them and decided upon the style I liked the best.

Step 6: Finishing the quilt!

Sew the binding on, keeping the stitch about 1/8 to 1/4 of an inch from the inside edge of the binding. Sew around all four edges, and you re done! I recommend washing in Dreft or any other baby detergent, especially if you have a helpful puppy like mine!
