And for those happy little stripes, pick out four Cotton Pure skeins in colors you love… There are over 30 shades to choose from! We used Tomato Orange, Fresh Lettuce, Lemon Mint, and Beach Rose against a  backdrop of Heirloom White for a fresh summer garden palette.

NOTES

GRANNY SQUARE BASICS

If you’ve never made a granny square, be sure to visit our How To Make A Granny Square tutorial. It’ll teach you everything you need to know!

RESET ROUND

As Granny Squares grow, they tend to skew, meaning they twist slightly and no longer form a perfect square. This phenomenon may be less noticeable with animal fibers (like wool or alpaca), but it will be more apparent with plant fibers (like cotton). To balance out this skewing and make a truer square, you will periodically work a “Reset Round,” where you will make (2 dc, ch 2, 4 dc) into each corner rather than the regular (3 dc, ch 2, 3 dc). These rounds will blend right into your Granny Square  and will ensure a big, lovely square!

PATTERN

Make the Boundless Granny Square Blanket by following the charted or written instructions, both below.
