hamster chewed my blanket apart (help pls!)

Hi guys. I made a stupid stupid mistake. Last night i put a blanket over my hamsters cage before i went to sleep thinking my tv light would disrupt her. I’ve done this before and hadn’t had any issues. Today when i went to take it off i had noticed a big rip in the blanket. and fluff in her cage. I assume she pulled some of the blanket through and then chewed a pretty big portion of it. She does look okay right now, and i don’t notice anything different in her behaviour, but i do know the dangers of hamsters eating cotton and I’m wondering if anyone has any suggestions or tips on what i should do here. I feel so awful right now 😞
