Rectangle

For working a straight edged lace ribbon you have to alternate the increase and decrease of one loop per row.

You will need the knowledge of the rectangular base shape for elongated petals as well.

Start with seven base loops.
The next row consists of only six loops, you decrease by one loop, just as if you were working a triangle.
In the following row you work two knots in the two outmost loops, increase the row by one loop.
For the next row, you only work six loops, decrease by one. You go on working in this manner until you are finished with rectangle.
