The Little Brother/Little Sister Security Blanket was one of the featured patterns in AllFreeCrochetAfghanPattern’s 2018 Security Blankets Charity Drive! I’m sharing the free crochet pattern for the mile-a-minute blanket with you, along with links to 6 more free crochet blanket patterns that are perfect for donation to Project Linus.

As my long-time readers know, I do most of my crocheting on my commute in New York City’s subways (hence the name Underground Crafter). When you’re working on a larger project, that’s not such a great idea. You may think that I live in this incredibly well lit (and incredibly neat) apartment shown in many of my blanket photos, like the one for the Classic Granny with a Twist Blanket shown below.
In fact, that’s my mother’s well-decorated apartment which also has great natural light. My own apartment has not-so-great natural light, a whole lot of cat hair, and we don’t have overhead lights in the living room or bedroom… so crocheting at night is not so easy. Or, at least, it wasn’t. Last year, the nice folks at Brightech contacted me about trying out one of their magnifier lamps. They have a great selection and that was sure tempting, but I asked to try the Montage Classic LED Floor Lamp in Oil Rubbed Bronze instead. You can watch it in action in this video.
When it arrived, MC and I were overjoyed. It came in a smallish box and we assembled it in minutes.

Just as I had hoped, it was easy to move around (though we usually keep it near the couch in the living room) and it has a beautiful soft light. It’s perfect for crocheting at night, especially with a darker yarn. Since it’s a warm LED light, it doesn’t overheat, even after hours of use, so I don’t have to worry about one of the cats getting hurt. The warmness of the light is also great because it doesn’t feel overly bright at night and it’s easy to use it right up until bedtime. You can see me how I kept my blanket strips organized in the Instagram post below.
I’m sure you’re wondering about the blanket by now. It’s a “mile-a-minute” blanket, meaning that it’s worked in the round in strips. The strips are portable and work up quickly since they are shorter and narrower than a scarf. Once you have all of your strips done, you assemble the blanket together. I wanted the blanket to be a very fun tactile experience, so I used Red Heart Dreamy and Dreamy Stripes, brushed yarns with a halo, and Red Heart Soft, a smooth and shiny yarn. Then, I joined the strips with a single crochet seam on the right side, so there are little hills of texture between each strip.

When AllFreeCrochetAfghanPatterns invited me to be part of their security blanket drive, I was happy to join in and become a Project Linus “Blanketeer,” using my hook to provide some cozy, handmade hugs to children in need.
Project Linus is a wonderful organization that has been connecting crafters with children in need for over two decades. They have distributed literally over 7 million (!) blankets. I profiled them in one of my charity spotlight posts and shared the free crochet pattern for the Rippled Security Blanket (shown above) a few years ago. And yes, that is my mother’s couch again.
You can find all the guidelines for donating to Project Linus here. If you have pets like I do, be sure to wash your blanket before sending it in. The nice folks at AllFreeCrochetAfghanPatterns took the finished project photos for me. This one shows a lot of the details….
… and this one (though photographed on the “wrong side”) let’s you see the size and drape of the finished blanket.

The Catherine wheels in your little brother/little sister blanket are wonderful.. they match up so much better then any I have ever seen.. I don’t like doing blankets but will do this one just to see how you manage to get those wheels to work out right.
