There are many ways for names (aka signatures) to get on a quilt. On some quilts all the names are done in the same method- i.e., all signed by hand by individuals or by a skilled signer, or stamped or stenciled, or inked and on other quilts there is a wide variety of methods. And on some quilts, all the methods are used.
Here is an 1840s signature album quilt from Delaware/PA in the "Grandmother's Pride" block with a wide variety of signing methods.
Delicious hand inked drawing
And yet another stamp.
