If you’re interested into adding an interesting vibe to your quilt, try making quilt borders with corner squares. You may easily cut the corners from plain squares of fabric or you can make them from patchwork or applique quilt blocks.
The first thing to know is that you may create borders from lengthwise or crosswise cuts of fabric. The crosswise grain cuts are typically around 42” long so you need to piece them together if the quilt isn’t small. You may want to go with this kind of grain cuts as they’re a bit stretchier than the lengthwise grain cuts.
Keep in mind that if you want to use the lengthwise grain, you need extra yardage for cutting the longer borders, parallel to the selvage of your fabric.
If you’re using pieced quilt blocks at corners, it’s important to know that the unfinished width of borders need to match the unfinished dimensions of the corner blocks. Let’s say that the border strips are 4-1/2” wide before sewing them to the quilt. This means that the blocks or the squares should be 4-1/2” x4-1/2”.
In case the corners squares join in multiple borders, you should cut squares or even make blocks that fit the entire border width.
You should to continue with measuring the quilt through its vertical midpoint by the same way you do it when joining borders to the quilt. Cut or build two borders to use on the left and right size of the quilt.
Measure the quilt the same way through its horizontal midpoint, cutting or building two borders to use along the top and bottom edges of your quilt.
Continue with sewing the side borders to the quilt, following the rules for butted borders. Sew the corner pieces to every end of the top and bottom borders too. You should also press seams towards the borders.
Match the seams where the corners and side borders meet and sew the borders to the quilt, matching all the way of the edge.
Always measure the quilt through its vertical point the same way when adding butted borders to the quilt. Don’t measure for borders along the outer edges of the quilt as they’re always a bit off.
Sew some strips or cut individual panels, in order to create two borders, the same length of the right and left sides.
Match the endpoints and midpoints and sew the side borders, using the tips for butted borders. Ease any differences and secure fabrics with some straight pins.
Don’t forget to also press seam allowances.
Measure your quilt through the horizontal midpoint and build two borders for the top and bottom edges of your quilt.
Quilt a block or sew a corner square to every end of both top and bottom borders, pressing seams towards the borders.
Continue with sewing the borders to the quilt, but make sure that you match it where the corners and side borders meet. Match midpoints all the way the whole edge.
One last tip
Try not to piece the long borders. If it’s possible, cut the whole border length from yardage for the shortest sides of the quilt. Reverse the directions above and start by sewing the short borders to the quilt.
