How to Easily Trim Quilt Blocks/Units to the Right Size

Getting quilt blocks to the exact right size can be tricky, but I’ve got a simple method to make trimming easier and more accurate! Follow these steps to ensure your blocks are perfectly sized every time.

Step-by-Step Trimming Method:

• Mark your ruler with washi tape:
  • Identify the size you want your quilt unit to be (e.g., 2 1/2″).
  • Place washi tape along that measurement on your ruler to create a quick visual guide.
  • This helps eliminate the need to constantly search for small ruler lines
• Use a Sharpie to find the center:
  • Locate the center of your desired size (for 2 1/2″, the center is 1 1/4″).
  • Mark the center point on both sides of the ruler where the meet.
  • this gives you a clear reference point for aligning the center of your quilt block/unit.
• Align and trim:
  • Match the center of your ruler to the center of your quilt unit to ensure an even trim.
  • Trim all the way around to achieve the correct size.
• Easily remove Sharpie marks:
  • Wipe off any Sharpie marks using a Qtip dipped in nail polish remover–good as new!

This method keeps your trimming accurate, quick, and stress free. Give it a try next time your quilt blocks/units come out the wrong size! VIDEO BELOW 👇
