Easy Mini Quilt Pattern: Catalyst Pillow Size Tutorial & Ideas
If you’re looking for a quick, satisfying project, the pillow size of the Catalyst Quilt Pattern is such a fun place to start.
This 20″ square mini quilt is made entirely from solids pulled from my scrap bins, and it’s proof that you don’t need a full fabric pull to create something bold and eye-catching.
A Scrappy Mix of Bright Solids
One of my favorite ways to use up scraps is by pairing a strong background with a handful of high-contrast colors—and that’s exactly what I did here.
For this mini quilt, I used all Riley Blake Confetti Cottons:
The deep navy background really grounds the design, while the brighter colors pop against it and bring so much energy to the quilt.
It’s a simple combination, but it makes a big impact.
The Perfect Quick Project
The pillow size of the Catalyst pattern finishes at 20″ square, making it ideal for:
- A quick weekend project
- Trying out a new color palette
- Using up scraps from your stash
- Making a mini quilt or pillow cover
Because the design is based on a single large block, it comes together quickly while still giving you that bold, geometric look.
Mini quilts require precise small pieces. Read my AccuQuilt Go review to see how this fabric cutting machine delivers accuracy for detailed projects like this pillow.
Simple Quilting That Lets the Design Shine
For the quilting, I kept things classic with a crosshatch grid using 50 wt cotton thread in navy.
This is one of my go-to quilting choices for mini quilts—it adds structure and texture without competing with the design. The straight lines contrast nicely with the angles in the block, giving the finished quilt a clean, modern feel.

Finishing Details
The binding is Paradise from Riley Blake Confetti Cottons, which pulls one of the brighter colors from the quilt top and frames it in a really fun way.
It’s a small detail, but it makes the whole piece feel polished and complete.
A Great Way to Practice Key Quilting Skills
The pillow size of the Catalyst pattern isn’t just quick and fun—it’s also a great way to build foundational quilting skills.
At the center of the design is an economy quilt block, a classic construction that teaches precision, layering, and how to build a block outward while keeping everything square. It’s one of those techniques that shows up again and again in quilting, so it’s a great one to get comfortable with.
This pattern also introduces 2-at-a-time Half Rectangle Triangles (HRTs), which are a super efficient way to create this often-intimidating unit. Once you get the hang of them, they open up so many design possibilities beyond this pattern.
Because this is a smaller project, it’s the perfect opportunity to try out these techniques without the commitment of a full quilt—making it ideal for skill-building while still ending up with a finished piece you love.
Why I Love the Pillow Size
There’s something really satisfying about finishing a quilt in a short amount of time, and this size delivers exactly that.
It’s quick, it’s scrappy-friendly, and it’s a great way to experiment with color without committing to a full quilt.
And honestly, it’s a little addictive! You might find yourself making more than one.
