Kyra, blogger at Black Threads, has a fascinating list of quilts and quilting related items she’d like to see featured at the new Smithsonian National Museum of African American History and Culture (NMAAHC).  Included with her list are links to web sites, blogs, or photos of the items.
Did you know there exists a quilt made by Harriet Tubman?
What about Rosa Parks’ sewing basket?
Fabric with African and African American images
Pearl Bailey’s needlepoint piece
A sewing machine used by Harriet Powers
These and many more Kyra mentions in her list of suggestions. 
After going through Kyra’s list, can you think of others to add?
