How do you decorate your house on club pony pals

To decorate your cabin, you first need to have cabin items in your inventory. These include flowers, paintings, ribbons, curtains and furniture. You can either receive items for your cabin as gifts (warning: very few cabin items, apart from flowers, are gift items) or buy them in the "For Your Cabin" catalogue at Klines.
To place an item in your cabin, click on the "inventory" button at the top of the page to look in your inventory. Click on an item you would like to put in your cabin. If there is only a "cancel" button, then you can't place that item in your cabin. However, if there is a green "hang up" button, click it to take the item out of your inventory.
Now that you have the item you want, a certain spot or spots with be highlighted in yellow. these are places where you can put that item. Click on the highlighted spot where you want the item to be to place it. Repeat until you're happy with your cabin.
To take an item down, go into your cabin and click on it. Choose "remove" to put the item back into your inventory.
