I would use the resolution center and file a damage claim for curtains and window blinds. I hope your blanket is washable and muddy stains will not stay.
Every decent guest would inform you about the damage and offer to pay for a replacement and your work. If they didn't, mean they are not good guests and you should review them honestly.
Remember - you have only 14 days to file a claim or before your next guest arrives. Include photos of damaged items, receipts if you have one and a link to the same product online.
