The Stripology Quarters Mini is one of the smallest rulers in the Stripology series of rulers. The slits are every 1/4in which gives it unique features not available in any other Stipology ruler. Designed to work with units of up to 6-1/4in, you'll be able to cut 1/4in and 1/8in increments as well. Easy to read black and white markings. Whole inch, half inch, quarter inch, and eighth inch increments are included. Markings for 1/4in and 3/4in cuts are included with cutting slots every 1/4in. Turn the ruler around and use the black and white squares to square up blocks in 1/4in increments up to 6-1/4in. Use the 45 degree lines to trim flying geese units down to 1/4in increments. 1-1/2in cuts are highlighted with black stars. Great for fussy cutting and trimming embroidered blocks. The flexibility of the ruler adjusts for the thickness of the embroidery giving you an accurate trim. Comes with fully illustrated step by step instructions.
