Setting Permanent Marker on Clothes

You can also hand stitch/embroider the signatures. I have a linen tablecloth from long, long ago that quests would sign and were embroidered over each signature. It looks really cool and you can use whatever color embroidery thread you would like for each signature. Yes, it's time consuming but it's worth it and a piece of artwork that cannot be washed away no matter what and will defintely last for your lifetime and beyond :-)

I don't know what kind of sharpies you use, but I have gotten accidental marks on my clothing that have NEVER washed out after numerous washing.

I had been using the brand name Sharpie (the expensive ones. I know you can get knock offs that have that name). I do use Sharpies to mark names on t-shirt necks that have stayed also. Sometimes alcohol will get some of the ink out, so stay away from that.

What a great idea!

Have you thought about going over the Sharpie signatures with fabric paint after your friends sign the jeans?

You can buy it at stores in the US like Michael's HobbyLobby, JoAnn Fabrics, and other craft stores. You used to be able to buy it at WalMart but most of the stores have really cut back on their craft departments.

Read the labels and directions carefully-several companies make a machine washable line of fabric paints, the paints come in gorgeous colours, some even sparkle and 'puff'.
