I've had problems with sharpies running lately. Not sure if they've changed the ink or if fabric is different.

I used a black pigma.

Ok, so I need to go get a pigma pen. Do you think JoAnn's sells them? I had back surgery two weeks ago and I'm still not allowed to get in a car. Wonder if my husband will mind going for me. LOL

Hobby Lobby carries the pigma pens if you have one near you.

If it's that inconvenient, I would just send the blocks unsigned. On the other hand tho, they don't need the blocks for several weeks more. You have a lot of time to go get one when it's more convenient.

Hope you heal well from the surgery! Back probs are no fun.

I didn't have one and the stores around don't sell them so instead I took the block to my embroidery machine and stitched my name on it, I didn't think they would mind as long as the block was the dimensions they wanted with the content they requested

I just ordered one from Amazon. Figured that was easier than sending my husband on a wild goose chase. :)
