I read that people usually put at least 10 drops to fill their empty carts. I can get 5 at the most without it pooling at the top and not absorbing anymore. I use a needle to poke holes in the fabric and that helps a little but I dont think Ive ever got 10 drops in a single cart. what am i doing wrong? refilling it too early? using too much polyfill? how long do you wait before drops? how long does it take to settle in? thanks.
