First, determine the colors and number of RUFFLES of each color block to be used to add up to the desired finished length. For the skirt shown our finished length was 11-12 inches- we had 4 sections of the skirt, with 3 ruffles in each section.
It is helpful to notice the knit fabric behind the ruffles- with the 1" ruffles, there are two strips behind the ruffles- one is opaque and one is more sheer. The line between these two strips is a nice straight line to follow when cutting.
Starting with the color block closest to the elastic top, cut half way between ruffles for the very top of the skirt.
Top of skirt
Now, cut your first section, cutting right up to the next ruffle- leaving both the opaque and the sheer strips of fabric intact. Repeat for all sections: for the second section, the top of the section should be cut between the ruffles and the bottom should be cut right up to the next ruffle - leaving both the opaque and sheer strips behind the last ruffle intact. For example, our second section was 3 ruffles- we cut right before the 4th ruffle. You will need both strips to overlap and zigzag the next color block series to join them together.
Bottom of color block section- with both strips intact and attached to color block.
Second section- 1 strip on the top and both on the bottom.
Repeat with the other color block ruffle sections. On the top, you will only need one strip, but at the bottom you will need both in order to overlap them and zigzag them together. You may have to cut off ruffles in order to give you the right amount of knit fabric... don't worry, you can use the ruffles for accessories or embellishments- (the tank top shown in the example uses 2 leftover ruffles).
Lay your color block sections out and re-measure.
JOINING COLOR BLOCK SECTIONS
Overlap the bottom of the first section with the top of the second section. Which fabric goes on top when zigzagging? Use the one that matches the thread you are using so that you will not have to change threads with each color block layer.
Repeat for all layers.
