Below is the pattern to follow for each 2″ granny square used in the CAL starting tomorrow! Keep in mind that these sqaures will require a small hook. I use an E for mine, and they come in just over 2″. I wanted them a bit bigger, as the blanket is for my husband. Just try out some different hook sizes until you find the one that works for you!
Ch 3 at begining of each round counts as first DC.
Round 1: Ch 4. DC 2 times in 4th st from hook. *Ch 3, DC 3 times in same st*. Repeat from * to * 2 more times. Ch 3. Join with sl st at top of Ch 3. 
Round 2: Ch 3. DC in next 2 st. *[DC, Ch 3, DC] in Ch 3 space. DC in next 3 st*. Repeat from * to * 2 more times. DC, Ch 3, DC in last Ch 3 space. Join with sl st at top of Ch 3 and fasten off. Use tapestry needle to work in end.
Joining your Granny Squares
There are a couple different ways to join Granny Squares, but slip-stitchign them together is my favorite! I would have taken pictures and posted them here, but Attic24 did a much better job then I ever could have! Check out here blog here for great instructions and photo tutorials!
Sweet Kiwi Crochet 
Thank you so much! I’ve never crocheted granny squares before!
Thank you, not done Granny squares this way before. Will be testing out what hook to use this evening!
I am so excited to find your CAL and I am going home to get started and try to get to the point you are at.
