When it comes to fixing unraveling resin wicker, there are a few things you can do. First, try to determine the cause of the unraveling. If it is due to sun damage, you can try using a UV-resistant spray to protect the wicker from further damage. If the cause is due to dry rot, you will need to replace the affected areas of the wicker. Finally, if the cause is due to insects, you can try using an insecticide to get rid of the pests.
