To finish the cowl, or to join any two ends of arm knitting together, use the mattress stitch.  When you seam with a mattress stitch, it puts the seam on the backside or wrong side of the knit fabric and makes the front side look magically joined.

 Mattress stitch:

// Start the mattress stitch by placing the two ends of arm knitting abutted up against one another with the right sides or knit sides facing up. Your working yarn should come from the top.  The ends should match in width. You may have to pull the cast on edge wider a bit to match up evenly. The stitches should give a little to allow this. Take care not to pull too far, though.
// Bring your working yarn underneath the first line of stitches on the right side (see the “v”?).  Pull it all the way through.
// Bring the yarn over to the left side and bring the yarn under the first line of sitches on that side. Pull it all the way through.
// Repeat on the right.
// Repeat on the left. Continue until you’ve seamed the length of your work. Leave the stitches you’re making loose enough so that the yarn you’ve run through looks like a line of stitches itself.

Weaving in the ends:

// Flip the work over to the purl side to weave in the end of the working yarn on the wrong side  of the piece.
// Weave the yarn under and over loops of the tighter side of the seam (the cast on edge).
// Tuck the yarn under multiple stitches in the seam and cut.

//  Go to the other side of the work to weave in the tail.
//  Weave in the tail in the same manner you did the working yarn. Cut end.

This cowl was made with Loops and Threads Cozy Wool.

YAY! Good job! You’re off to go arm knit to your heart’s content. I hope it’s been simple enough and that you’ve enjoyed the process. If you’ve liked this tutorial, share it with your friends! I’ve been developing all sorts of amazing patterns and things to make with your new arm knitting skills, most of which will be included in my upcoming book, to be published by Potter Craft in Fall 2015. I wish book publishing were as fast as blog publishing!  Until then, go strut your stuff in your new cowl!
This cowl was made using Lion Brand Wool Ease Thick and Quick.

    is there a chance that i can knit a nice, thick blanket with this technique? i think it would be such a great gift!

    • Absolutely! Arm knitting makes a great blanket. It would make a fabulous gift. Just cast on as many stitches for the width of the blanket you want and have at it! You can figure that out by measuring the width of 10 stitches and then increasing the number of stitches to get the width of blanket you’d like. For example, if 10 stitches= 12″, then 20 stitches would be 24″ and so on. I have some gorgeous blankets coming out in my arm knitting book, which you will be able to by in Fall 2015.

      • Thank you! That was my exact question too. I’m looking forward to some cool Fall nights of arm knitting :)

    What a fun project I’m going to buy my girls some wool and pass on your knowledge. Thank you so much for sharing. The next time you feel a lovely warm hug. You will know it’s the bonding you have created for my girls and I while we have a Sunday chat and a knit

    • Sally, You just brought the biggest smile to my face! Thank you for such a charming and warming comment. Happy arm knitting!

    How can I just turn this into a giant chunky blanket?

    • Hi Lindsay,
      You’ll want to cast on more stitches. If you imagine that this cowl is about 12″ across, I would cast on triple (30) and go until you get to the length you’d like . . . I’m hoping to post a blanket tutorial come the fall. Enjoy!
