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.
As a side note, she was wearing a fabulous lime green vest that she knitted as part of the knitting class she teaches.
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.
