If any of you have children, no doubt they want to make home made slime. It is made from white glue, liquid starch and water. My youngest dropped it on the carpet and I was tasked with the removal. What worked for me was white vinegar. I cut a paper towel in 1/4's and wet with vinear and then use dry one to blot. Keep doing until stain is gone. I did the wet/ dry method about 20 times and it was gone. Put this under your hat and keep calm if this happens to you.
