The reason I used 14 stitches is because 14 stitches produces a width that fits within the handle nicely….if your mug handle is smaller or wider just decrease your stitches or increase your stitches to get the correct width.
This seed stitch is: one knit stitch followed by one purl stitch.
These two knitting stitches are continued like this: knit 1, purl 1, knit 1 purl 1 ect until you have completed all 14 stitches.
In the next row and still using the seed stitch, create two buttonholes for your buttons. Knit the buttonholes so that they are evenly spaced across the row.
To make buttonholes:
a. Work to buttonhole location.
b. Bring yarn forward and slip the first stitch on the left needle purlwise.
c: Bring the yarn to the back of your work.
d. Slip the next stitch on the left needle purlwise onto the right needle.
e. Pass the second slipped stitch on the right needle over the first stitch (as if to bind off).
Repeat Steps d and e until the buttonhole is the right size.
f. Slip the last bound-off stitch onto the left needle.
g. Turn the work and use the Cable Cast-On method to cast on one more stitch than you bound off. Insert the needle purlwise instead of knitwise between the stitches so that the top edge will better match the bottom edge of the buttonhole.
h. Turn the work.
i. Slip the first stitch on the left needle to the right needle and pass the extra cast-on stitch over the slipped stitch. Work the remaining stitches on the needle.
4. Now knit three more rows of seed stitch.
5. Cast Off all the stitches:
