Common Mistakes to Avoid

1. Toothpaste Too Thin

Reason: Using too much water or not enough baking soda creates a runny, unusable consistency.
Solution: Add more baking soda gradually until you reach a firm, pliable dough-like texture.

2. Play-Doh Too Dry and Crumbly

Reason: Insufficient water or too much flour results in a Play-Doh that's difficult to mold and breaks apart easily.
Solution: Add a tiny amount of water, a drop at a time, and knead until the dough becomes smooth and pliable.

FAQs
