The Problem: Your kids leave the lids off their markers and they've dried out.
"When markers start to dry out, dip the tips into white vinegar and set so that the tips are standing up. Wait about 5 minutes, then blot the marker tip on some paper until the color starts to show. Place the cap back on, and let sit overnight"
Another tip is from Trisha at Inspiration Laboratories.
"When markers start to dry out, you can also dip the tips in water and paint with them. It will have a watercolor effect"
The Problem: Your preschooler keeps trying to string beads, only to have a tough time managing holding the string and getting the beads on.
The Solution: tape one end of the string to the table! Now your little one only has to hold one end of the string and they have their other hand free to pick up beads and string them on.
