Crochet Afghan Block – Supernova Square

Explore the shifting, layered textures of the Supernova Square. A starburst at the center sets this crochet afghan block in motion, radiating outwards into puffs, shells, ridges and more. With such varied textures, this blanket square works equally well with one color or many!

Moogly 2019Afghan CAL

This pattern was designed for the Moogly 2019 afghan CAL. If this is the first you’ve heard about it, go check it out! Also be sure to take a look at the block 20 post to see how Moogly’s version of this square turned out.

Red Heart With Love Yarn

I originally received this yarn for free from Red Heart for my 2018 Moogly Afghan square. I had plenty left over from that pattern, and I just love how well these colors go together. Red Heart with Love is a softer yarn, and comes in a wide array of colors to choose from. What colors are you using for your blanket?

Working into the 3rd loop

The textured section of this square is created by alternating between normal half double crochet stitches, and half double crochet stitches worked into the third loop. The third loop is in the back, and just below the front and back loops that we normally work into.
