Omnigrid Quarter Inch Seam Marking Ruler Trio

$ 19.95 USD $ 22.50

The Omnigrid Quarter Inch Seam Marking Ruler Trio comes in three convenient lengths: 4", 6", and 12". Their center lines are exactly 1/4" from both edges of the rulers, providing an excellent reference line for marking 1/4" sewing lines, adding and checking seam allowances and marking 1/4" quilting lines. 

Easy to use tool is great for making HST's (Half Square Triangle Units) and hourglass units. This is the tool that I personally use for marking lines on my HST's.

  • Mark 1/4-inch sewing lines on patchwork pieces with this nifty set of tools
  • It is a quick and easy method for half-square triangles and hourglass units
  • Features an acrylic construction with easy to follow black and yellow markings
  • Instructions for two patchwork blocks included
  • Pairs great with our Frixion Pens!

Do not use with rotary cutters, knives or other cutting instruments; rulers are designed for marking use only.

I was so glad when I saw your e-mail in my box

I was so glad when I saw your e-mail in my box, I have been looking for 1/4-inch ruler for quite a while now, so when I saw your rulers, I ordered them. I haven't tried them yet but make a lot of hst and these will really come in handy.

We are so glad you found our rulers! We lost them for awhile and were so glad when we found another source. We swear by them when making HSTs. Thank you for your review!
