Story Behind the Rainbow Quilt Block
The Rainbow block came to be out of my own creative play! It’s been a few years now that I’ve been sneaking in some drawing time in the mornings. It’s such a lovely and calm way to start the day. And it’s led to the creation of some really fun motifs.
What I love about rainbows is that they represent hope and colour – ha! In the last several years, I’ve been lucky enough to witness a few double rainbows and also a rainbow that showed the entire arc. That was quite fascinating to see.
So, this cutie of a modern block is intended to bring joy to your quilt and remind you that hope can be found when we least expect it!

Composition Play
The Rainbow block is such a fun design to have in your quilty back pocket. The curves help you add a softened organic feel to your quilt composition.
Those gentle curves allow you to break up the angularity of the other block designs and encourage flow through your layout.
Remember to play around with the block layout as it’s shown in the pattern and the reverse/rotated options. Adding these types of variations to your quilt will lead to more intrigue and a unique to you layout!
Quilting Technique Featured
The quilting technique featured in the Rainbow block is the classic Drunkard’s Path quilt block. If you’ve made the Lunar Eclipse quilt, then you’ll have a solid base to jump off from.
The challenge here is that I’ve incorporated some skinny curves in the block. This is fun from a design perspective as it adds lots of detail and interest to your quilt. But getting those curves to line up and avoid the wonk is where things can get tricky!

Top Tips
This probably sounds familiar as I know I say this quite a bit, but it’s because it’s true – the more you practice sewing curves, the easier it gets. I promise!
If I think back to the first curve I ever pieced, it was quite the learning experience – ha! You can see that one here.
Over the years, I’ve stitched up my fair share of curvy blocks and these are my top tips:
Cut accurately
I know, it goes without saying that you need to start with properly cut pieces, but when you’re joining pieces with so much bias edge, it makes it that much easier when your pieces are cut to the proper starting size. The Mouse Trap acrylic templates help immensely with accurate cutting!
Pins are your friend
While I love piecing my curves without pins, that’s not where I started. I think there’s a huge merit to learning how to sew curves with pins. It allows you to ‘see’ how the pieces are going to be joined, and it keeps things tidy and organized at the machine. Once you’ve gotten comfortable piecing curves with pins, you can try omitting them and seeing what difference that makes!
Pressing matters
Be mindful not to iron your curves, you want to press them instead. What’s the difference?! Ironing is that back-and-forth motion you do when ironing your clothes. Pressing involves placing your iron, letting it do its thing for a few seconds, then lifting the iron up and placing it back down in a new spot. This helps prevent your fabric from shifting and stretching on you. A wool pressing mat can help keep your pieces from stretching out too! This tip goes double if you’re working with linen or wovens, as they like to stretch out on you even more.
Relax
I know, I know, all those bias edges and pins, and it’s instant quilty stress! A key to nailing quilting techniques is relaxing into the stitching and having confidence in yourself. The more I say that I can do it, the more I can do it! Try it and see how your mindset impacts your quilty play 😊

Caution
Things can get wonky really quickly with the Rainbow quilt block. Be careful that you’re not pulling or tugging on your fabric as you piece and press your block. Those bias edges like to stretch out on you, which will make it more difficult for you to keep the block alignment on track.
My top tip here is to be gentle and use a light touch!

Would using some light weight spray starch on each piece before cutting help in reducing unwanted bias stretch? or do I need a little stretch just to get it around the bend?
I don’t use spray starch in my quilting, but you can absolutely give that a go, Cynthia! It will add a little more structure to your fabric and should help prevent some of that stretch. A light weight spray starch (instead of a super strong hold) is probably your best bet.
