Last month, I shared the Diagonal Rainbows Baby Blanket pattern with you. I had so much fun using this variation of the diagonal box stitch (also known as the corner-to-corner or c2c technique), that I decided to design a 6″ (15 cm) square using it.
This square is my first contribution to the Mystery Lapghan Crochet-a-long, a fun crochet event featuring 36 6″ (15 cm) squares by 30 crochet designers.
This post contains affiliate links. The yarn for the sample was generously provided by Lion Brand.
You can read more about the CAL here, or join the Facebook group to chat with participating crocheters.
The great thing about using this pattern for the CAL is that it can easily be adjusted to match your specific gauge. I included a video tutorial at the bottom of the post in case you are new to corner-to-corner crocheting. I used different hook sizes for the sample square pictured above and the one in the video, and each required a different number of rows to reach the same size. You can make similar adjustments to your own square!
Don’t forget to share a picture on Ravelry or with my Facebook page if you make one!

I never done a C2C I understand the video
Glad the video could help, Tammy!
I have been seeing this technique around a lot lately, and I am really liking the look of the pattern. I definitely need to give it a try, and what a more perfect time, than as part of the mystery lapghan?!
So true! CALs are the most enjoyable way to try new things, Alexandra!
is there a print link to print just the pattern, and not all the additional comments and ads?
Lisa, thanks for stopping by. If you print using your web browser, you should have the option to print only certain pages and to exclude the comments.
Is there somewhere that lists how many colors are needed for the lapghan and how much yarn of each?
Carmen, there isn’t such a document. What I’ve noticed in the Facebook group is that some people are using scraps and others have 3 or 4 colors they are using for each square. I’ve found that most 6″ squares use less than 60 yards of yarn, so I think it is a good amount to guestimate for each square.
Thank you for the video! I too have been seeing the C2C, mostly in blankets, and thought a CAL was the way to try it, but somehow I wasn’t managing to “get it” from the written instructions. I never look at crochet or knitting videos, but I’m glad I tried this one – and I’m very proud of my completed 6″ square! I’m sure it’s not the last instructional video I’ll check out now 😀
I’m glad to hear the video helped, Victoria!
Am I the only person who gets an error saying content is unavailable whenever I click on any link for the Facebook group for the Mystery Group CAL? If so, why?
Rose, I’m not having that problem myself, so I’m not sure why you are getting error messages.
I tried the link again and it’s still happening. 🙁 Too bad for me. Thank you for the response.
Rose, I just sent you an invite to the group. I hope that helps!
I am having that problem also.
Lisa, what problem are you having? Can you share the details so I can help?
What a beautiful, common sense pattern – brilliant thank you Lisa!
Thanks so much, Marsha. I’m glad you enjoyed it.
I used this pattern years ago to make an afghan in my sons high school colors (1985)! But it took me nearly 8 years to finish it!! I made 80 squares with royal blue on one corner, white in the middle and steel silver grey on the other corner. Sewing it all together was the hardest part. In fact my sister-in-law finished sewing the last half together as I had some health issues that kept me from working on it and it was stored away for some time. I had the pattern for one done in red, white and blue. It goes together with like colors touching and it looks like large blocks of blue and grey framed in with wide rows of white. I’ll try to get a picture taken and put in my computer so you can send me an email request for here. I’m on Facebook but don’t have any pictures of some of my crocheted projects I’ve done. I’m 71 and have crocheted since I was nine when my sister taught me to make a chain till I got all the stiches the same size!! Enjoyed the tutorials here on this site. Thank You.
Thanks for your kind words, Wanda. I learned to crochet when I was 9, too. The blanket sounds beautiful!
Thank you, I really enjoy getting these patterns.
Thank you very much for putting this out. Looked at several other instruction sets before I found this and your pattern is the clearest to follow. As someone who is self taught with tutorials, this clarity is extremely helpful. Thanks again.
