I tried Pigma & Fons & Porter. They both ran when I washed the block.
Any ideas?

Did you heat set?

yes

How about the Frixion pen-?

Did you pre-wash the fabric to remove the sizing?

Have done lots of friendship quilts with the signatures using several different colors of Pigma pens. Absolutely no problems if the fabric has been prewashed with no fabric softeners added. After all the signing is completed you should press again - very important step. It is called heat setting the ink. Washing afterwards is OK - recommend cold water and Orvus paste for detergent.

I have used both pigma pens and ink jet printers without any problems. I just make sure I do the washing of fabric before and the heat set after. I also just use regular detergent on all of my quilts with fabric softener.

I wash the fabric and do not use fabric softener or dryer sheets. I have used Pigma pens with good results. Sharpies do wash out eventually.

You aren't using white on white are you? If so, be sure to write on the back rather than the front.

Maride recommends Copic pens. Thanks all

the pigma pens to use are Micron Pigma pens- they are permenent- archival quality= acid free- do not bleed- do not run- do not fade- are made for textiles-
just any on the grocery store shelf pigma pen is not a pen for textiles..
they do not need to be heat set- it does not matter- if the fabric is pre-washed or not- they come in sets of colors= or black-they have 3 different tip sizes.
many many artists use them because you get a clear line on any textile- they do not get the fuzzy edges like other markers give you

I have not tried ink jet without Bubble Jet Set. I am going to try it.
