A useful technique is using a sewing machine to line the edges of hand knits with fabric bias tape. This is a good way to keep knit edges from curling up, and to strengthen and stabilize an edge that has to support button holes or other load-bearing features. It can also be very decorative if you find a complementing fabric.
The following example is from the Nightfall Lace-Up sweater.
The photo above is the reverse side of the side-placket encircled below. The photos in the instructions that follow were taken while lining the front placket, also encircled below.
Cut 2 pieces of fabric on the bias (45 degrees, to the fabric selvedge edge.)
- Width = 1.5”
- Length = Length of the edge being lined + 1”.

Pin one fabric piece to each edge as shown below. (Right side and wrong side of same edge, shown below.) Fold down, and pin under, any excess length.
Stop at the corners, raise the presser foot, turn your work, and sew straight across both pieces of fabric where they come together at the base of the bust, as shown below. Back stitch a few times across this line for extra strength.
And you are done! Turn it right side out and enjoy your work:)
