While the majority of the sheet patterns have a white background, there are quite a few colored ones. Searching by background color can be helpful – especially with floral prints. So Amanda and I have both added this feature to our sites. All new prints will automatically be categorized, but there are over 1900 already catalogued that I will have to go back and update. As always, if you encounter an error, missing info, anything at all that you feel should be addressed, please let me know!
