I used pretty much matching yarns but it would be fun to do a pair in stripes or contrast!
Knitted Elbow Patches
Yarn: Cascade Yarns 220 or Knit Picks Wool of the Andes worsted
Needles: US size 6
Gauge: 5 stitches per inch (but gauge is not crucial)
Notions: Small hand sewing needle, matching cotton sewing thread
Abbreviations:
K2tog - Knit two stitches together (decrease one stitch)
M1 - Make one (increase one stitch)
SSK - Slip, slip, knit (decrease one stitch)
Stockinette stitch: Knit one row, then purl one row. Repeat.
Directions:
Cast on 10 sts (I prefer long tail method)
Purl 1 row
Next row (increase row): K1, M1, knit to last stitch, M1, K1
Repeat last two rows until you have 16 sts.
Work even in stockinette stitch until piece measures 3” from beginning.
Next row (decrease row): K1, K2tog, knit to last 3, SSK, K1
Purl 1 row
Repeat last two rows until 10 sts left
Bind off all stitches on next row. (This is a purl row but you can bind off either knitwise or purlwise.)
Make 2. The edges will be curly so block if desired.
To help place them symmetrically on each sleeve, use a measuring tape to measure up from the cuff to edge of patch, and over from patch to sleeve seam.
To keep pins from getting stuck, slide a wide clear quilting ruler or small hardcover book inside the sleeve, then use straight pins to pin patches in place. Uncurl the edges as you pin.
Here you can see the patch pinned in place, getting ready to sew, and the clear ruler in the background.
Sew onto the elbow holes of your sweater with cotton sewing thread. I put an extra-large wooden darning egg (available here) inside the sleeve, but if you don't have one, just put your hand inside, or keep the clear ruler or small book inside.
Use an overcasting stitch to attach: scoop a little of your sweater fabric, then come up through the patch from below, letting the thread wrap around edge of patch.
If you make them, let me know what you think!
