At our May 16th meeting, we had an eye-opening exercise in which two teams tried to organize a couple of dozen fabrics according to value. What it taught us is that value is not always an absolute - it can depend on the light in the room, sometimes the scale of a pattern, perhaps the fabric with which you choose to compare it, and often the person who views the fabric. Even so, the two teams organized their fabrics fairly similarly.
We were also shown how value can change by changing the density of a thread, a shown below. These were all done on a sewing machine with a single thread.
One of our Fearless Leaders of the program, Veronica, also put together 11 quilt blocks of the same pattern but with fabrics of different values, showing how they look completely different using different values, and how holding them beside each other also gives a different result in how the block appears.
Last but not least, Julie, who is new to the guild, created a beautiful wall quilt that perfectly exemplifies the importance of value in making an appealing quilt.
