The Linked Arms technique is for the boundary
between two colors, where there would normally
be a seam. It requires a little juggling, but it’s a
way of working intarsia, in the round, without
seams. So, this pattern actually uses the regular
twist-when-changing technique of preventing
holes in intarsia along with the Linked Arms, to
avoid a seam. Increases and decreases, not
special intarsia techniques, create the triangle
motifs in the sleeve.

Thanks to eagle-eyed knitter:
On pdf page 5, 3rd paragraph, 5th line. The pattern says;
“Drop color 1. Turn, with color 2, purl 39 stitches.”
I think “Turn” here is not necessary, because just before this part, we turn the side, make purl2, purl 2 tog and continue on purling after this.

The website that previously hosted this has dropped all of my old patterns. They are currently unavailable, but I may reissue them at another time.
