We have tried: We used the fake blood on white cotton canvas. Its consistency was liquid and thick for a long time, it dried very slowly. After a long blow-dry at high temperature, the effect of "dried" blood came only after several hours. The paint was sticky in places of larger drops even after 48 hours, but it did not stain in any way. After 52 hours, we washed the paint from the canvas, there were no stains on the fabric.
