I've just gone to see Diane's site and "her" interpretation of copyright. She is partially within her rights and partially way off in left field. She CAN ask that we not use her personal-private-took-them-myself photos and we can't photocopy and then sell her patterns. Fine by me. The rest? ummnnn, not...
However, she did not invent the Texas Star, or if she did, she must be close to 150 years old...and she is certainly not the originator of Native American designs.
What saddens me as a pattern designer is that, by trying to protect her business, she is alienating us, doing herself a grave disservice and losing business.
