I have been mailing mine with a regular 1st class stamp. I took my first batch to my little town PO and asked for them to be hand-canceled. She said no one anywhere will do that anymore. It is ALL by machine.
Was miffed!
The next time I made some I took them to a bigger town where we shop. Without asking, the worker immediately hand canceled all of them.
I now take them all there.
The recipients are all pleased to receive one!
I only do piecing and quilting on them. No thick embellishments. This spring I sewed down a silk flower piece.
