Patch Tool
Fitting Shapes Together to Form Designs

Quilters and other designers sometimes start by producing square patches with a pattern on them. This patch is then used over and over again to produce a larger pattern. Create your own patch using the shapes and tool below.

Instructions

Available
Shapes
  1. Click on the arrow, then on a shape to bring that shape into the work area.
  2. Click on the rotate button and then click on the shape to rotate the shape.
  3. Click on the flip button and then click on the shape to flip the shape.
  4. To stop rotating or flipping, click on the rotate or flip button a second time and the arrow button becomes active.
  5. To move a shape, click and drag it to the desired location.
  6. To erase a shape click on the erase button then on the shape.


Activity

Once you have designed your own patch, think about the following questions.

  1. What features does your patch have that you find interesting?
     
  2. Was there a shape that was harder or easier to fit with other shapes? If so, why?
     
  3. If you put several copies of your patches together, how would they match up?
     
  4. When did you have to use the flip tool? Could you have used the rotation tool instead?
