Most patterned fabric is screen printed using screens of 12" or 24". Each of the colour dots or symbols on the selvedge indicates a screen that has been used to print on the fabric. One colour at a time is printed.
There are now digitally printed fabrics. More colours can be layered creating more detailed images with more depth and in different widths of repeats. These fabrics cost more but can be well worth the price for creating artful quilts.
We have one bolt from Hoffman fabrics in a line called Wanderlust. Brenda, of 'Among Brenda's Quilts and Bags', has a free pattern on the Hoffman website using the line. I chose the one print which includes the Eiffel Tower because the Ailsa Craig Community Quilt Festival is welcoming quilters from France next May. Also, there are a number of quilters in our area that have travelled to France and want to create a memory of their adventure.
Keeping in mind the quilters from France are coming, we are ordering other fabrics with that theme in mind. French General designs from Moda are based on antique French textiles. The Rue Indienne line is here and the Bon Voyage line is due in April. These are screen printed.
