Color Changes Make Every Granny Square Unique

One of the most exciting things about crochet granny squares is their infinite color possibilities! The same pattern can look completely different depending on the yarns you choose. With this iPad cozy, you have two great options:

1️⃣ Use a single long-color-changing yarn (like Caron Cakes, Chroma Worsted, or Lion Brand Mandala) and separate the colors before crocheting for controlled color placement.
2️⃣ Combine multiple solid yarns to create a planned gradient or contrasting color effect.

NOTES

Cozy is made with granny square motifs that are joined together as you crochet. You can start with any motif on the layout and join motifs in any order you wish.
Separate the colors in the cake into the 5 different colors listed in the materials section and shown in the pictures.
Securely weave in the tail of the adjustable ring to guarantee that it doesn’t pop open with use.
Weave in the tails as you go. Do not wait until the very end to weave them in.
Each round of color is fastened off at the end and the new color is rejoined using standing double crochet.
If you would like a cozy a different size, you can make a slightly larger or smaller motif. For instance a 5” [12.5 cm] motif, makes a 14” [35.5 cm] wide by 10.5” [26.5 cm] tall cozy. Also a 4” [10 cm] motif, makes a 11.25” [28.5 cm] wide by 8.5” [21.5 cm] tall cozy.
