Crochet Pattern: Tadley’s Diagonal Blanket

This diagonal baby blanket crochet pattern is perfect for those of us who are excited as we start the project and then want to get started on the next project as soon as we get about half way through the pattern! This is also a perfect beginner project to try out your double-ended Tunisian crochet skills!

The yarn for the sample was generously provided by King Cole.

My regular blog readers know I have a soft spot in my heart for baby blankets. I actually love crocheting blankets in general, but by the time I get about halfway through a full sized blanket, I’m usually questioning my own sanity. Baby blankets are much faster to make, and they always seem to be cherished by parents and babies alike.

Last year, one of my dearest friends was expecting her first born, and I knew I had to make something special. I had recently finished the sample for the Checkerboard Cable Scarf that was published in Love of Knitting‘s Holiday, 2013 issue.

The generous folks at King Cole had sent me quite a lot more Merino Blend Aran than what was required for the scarf, and I knew my friend was having a boy.The white and blue seemed like just the right colors for his blanket, and the easy care of the superwash wool seemed a great fit for a newborn.

I used double-ended crochet because it looks great – but different – on both sides, and it makes a nice, thick blanket. After all, Tadley was due in late December, so I thought he might need something very warm for his stroller or car seat during the winter.

To combat the love-hate relationship I develop with all of my crocheted blankets during the last few rows, I crocheted this on the bias, increasing towards the center and then decreasing until the end. Once I reached the center, each row was shorter than the one before it, so finishing the blanket was a breeze.

Well, almost a breeze. On the last few rows, I ran out of yarn. I ordered one extra skein in each color, and by some strange miracle, both skeins were from the same dye lots as the yarn I received from King Cole almost five months before.

This blanket is very lush and thick, and works equally well as a playmat in the spring or a stroller blanket in the winter. Gauge isn’t critical, and it can be easily resized (though you may need more or less yarn). I used a flexible double-ended crochet hook made from my Denise2Go interchangeable crochet hook set, but my pattern testers used other types of double-ended crochet hooks, including long, straight hooks. Enjoy!
