The Seven of Pentacles card indicates that you think the time is right to make a decision about what to do with your carpet. This means you are ready to make a thoughtful and considered decision, while staying true to yourself and your principles.
The reversed Page of Pentacles indicates that you feel a deep sense of nostalgia and connection with this object. You appreciate the emotional value of the object, but perhaps also the lack of it and the impossibility of keeping it.
The last card, the reversed Three of Cups, indicates that you need to make a decision based on your current situation. Perhaps you need to focus on what you can do now rather than on how you feel about the item.
The cards suggest giving your grandmother's old carpet as a gift. Not only is it important to respect the nostalgic and emotional feeling you have for this item but also to make a reasonable decision based on your current situation. Since the item is precious and emotionally important, gifting it may be the best choice for you. It would allow someone else to enjoy its value and keep your grandmother's memory alive.
