Diamond in a Rectangle
Diamond-in-a-Rectangle Unit
Construct a diamond-centered rectangle by joining mirrored side triangles to opposite edges and trimming to exact unfinished size.
- Cut the center rectangle and side triangles slightly oversized according to your unit size plan.
- Mark the midpoint on the long edges of the center rectangle and on the long edge of each side triangle.
- Align midpoint to midpoint, then match corners and sew one triangle to each opposite side with a 1/4 inch seam.
- Press seams away from the center rectangle and repeat for the remaining sides if required by your variant.
- Trim the completed unit to unfinished size, keeping at least 1/4 inch seam allowance beyond all key points.
Pro tip: Treat mirrored triangle pairing as mandatory; if both sides are cut in the same orientation, the diamond will lean and the unit will not trim square.
Midpoint Triangle Join
Triangle-to-Edge Join
Attach a regular triangle to a square or rectangle edge by matching center points first, then sewing a standard 1/4 inch seam.
- Fold the base edge (square or rectangle side) in half and finger-press to mark its midpoint.
- Fold the triangle along its base to mark the midpoint of the long edge.
- Place triangle and base right sides together, align midpoint marks first, then align both corners and pin.
- Sew with a regular 1/4 inch seam from one end to the other without stretching either edge.
- Press the triangle away from the base and trim dog ears if needed before adding the next seam.
Pro tip: Pinning the midpoint first prevents the triangle point from drifting left or right; this is the key to keeping points centered across repeated units.
