The Hermitage Museum has done an excellent job of bringing their collections to everyones fingertips.
Load the page listed above and select Textiles. They have nearly 400 textile pieces from their collection availabe to view. Best part is once the item comes up allow it to fully load the high resolution image and then with your mouse you can “hover” and examine every detail by the enlarged image that comes up tracing your path. Amazing. Need a stress break? This is the place to go.
