How to Speed Up Snowball Quilt Blocks

If you’ve made quilts with snowball corners, you know they can add up quickly. Drawing a diagonal line on every single square works well and gives accurate results, but when you’re making dozens or even hundreds of snowball units, that extra step can take quite a bit of time.
Over the years, I’ve started using a simple shortcut that helps speed things up without sacrificing accuracy. In today’s video, I’ll show you how I use a strip of washi tape as a sewing guide so I can skip drawing those diagonal lines altogether.

The Traditional Method
Most quilt patterns, including my own, are written using the traditional method of drawing a diagonal line from corner to corner on each small square. It’s reliable, easy to understand, and works beautifully for quilters of every skill level.
That’s still the method I recommend in my patterns because it’s universal and easy to follow.
A Faster Way to Sew Snowballs
Once you’ve made a few quilts, though, you may find yourself looking for ways to speed up repetitive steps.
One of my favorite tricks is placing a strip of washi tape on the bed of my sewing machine to act as a visual guide. Instead of drawing a line on every square, I simply line up the corner with the tape and sew.
It takes a little practice, but once you get comfortable with it, it’s a technique you can use again and again on future quilts.
Why I Like This Method
For quilts with lots of snowball units, skipping the marking step can save a surprising amount of time.
I also enjoy keeping the sewing process moving. Rather than stopping to draw lines on every square, I can sit down at the machine and focus on sewing.
It’s a small change, but those little efficiencies really add up over the course of a large quilt.
Practice First
If you’ve never sewn snowball units without marking the diagonal line, I’d recommend practicing on a few scraps first.
Once you get a feel for lining the square up with your guide, it becomes second nature.
