After you knit a blanket, you can add a knitted border with the same or a contrasting colour yarn. For a neat finishing touch, use a garter stitch border and mitre the corners of the border.
There are two methods for making a border with mitred corners. In the continuous border method, knit the border all the way around the edge of the blanket. For a joined border, knit separate borders for each edge and sew them together at the corners.
Pick up and knit the stitches along the top edge of the blanket using a large circular needle. Pick up one stitch for every stitch.
Place a stitch marker at the corner.
Pick up and knit stitches along the side edge, picking up 3 stitches for every 4 rows, and place another marker at the corner.
Repeat Step 1 along the bottom edge and Step 2 along the other side edge, placing markers at each corner. Join the yarn to the first stitch.
Purl each stitch, slipping the markers as you come to them.
- Knit 1, knit into the front and back of the next stitch, knit to 2 stitches before the corner marker, knit into the front and back of the next stitch, knit 1, slip the marker. Repeat from the * until you complete the second round.
Repeat steps 5 and 6 until the border is the width that you want.
Cast off and weave in the ends.
Pick up and knit the stitches along the top edge of the blanket. Pick up one stitch for every stitch. Turn the work.
Knit 1, knit into the front and back of the next stitch, knit to 2 stitches before the end, knit into the front and back of the next stitch, knit 1. Turn the work.
Knit each stitch. Turn.
Repeat steps 2 and 3 until the border on the top edge is the width that you want. Then bind off.
Repeat steps 1, 2, 3, and 4 on the bottom edge. Be sure to knit exactly as many rows for the bottom border as you knitted for the top border.
Pick up and knit the stitches along one side edge of the blanket. Pick up three stitches for every four rows. Repeat steps 2 and 3 until you have knitted the same number of rows for the side border as you knitted for the top border, then bind off.
Repeat step 6 for the other side edge.
Sew the corners together using a mattress stitch. Weave in all the ends.
A continuous border is more appropriate for smaller blankets such as baby blankets. A joined border is appropriate for any blanket. When you make a joined border, you can use a different colour for each side of the border.
