How to Square and Trim Finished Quilt Blocks

Want to learn how to make a quilt with an easy online workshop – totally free?

Sign up for Let’s Make a Quilt here. You’ll learn how to get started, the tools and supplies you’ll need, and how to make a quilt from start to finish using Quilt As You Go and applique with fusible adhesive.

It’s the easiest, most fun way to make an applique quilt. You can do it!

I usually follow these steps to make any of my Quilt As You Go applique quilts. . .

  1. cut quilt blocks (and batting) 11 inches square
  2. quilt the blocks
  3. applique the blocks
  4. outline stitch the applique
  5. trim quilt blocks 10 1/2 inches square
  6. sew the quilt blocks together
  7. press seams open
  8. baste to backing
  9. quilt
  10. bind

I’ve had several requests for more information about step 5 – specifically a video showing how to square and trim quilt blocks. It’s actually really easy – if you have the right tools.

Here’s how. . .

I don’t have very many rotary cutting rulers – but this is one that I really can’t imagine doing without. I highly recommend it if you do any quilting at all.

This is the exact ruler that I use to trim quilt blocks* – the one you see in the video. It’s not inexpensive, but Joann’s always seems to have a good coupon and that can make a big difference. 🙂

For bigger quilt blocks (like the ones in this free Polaroid Quilt Block Tutorial) I use an even bigger ruler – one that’s a whopping 20 1/2 inches square! It’s a little unwieldy, so I only use it for the bigger blocks.
