Your three-season room is basically an extension of your house. It’s not heated and insulated, but it’s a comfortable space that’s covered so that you can sit and read a book or relax as you would indoors. That means you’ll want privacy sometimes, and one way to get that is to make ruffled curtains using this tutorial from HGTV. Make them from fabric that can handle the elements since they’ll be exposed to heating and cooling over time that can cause moisture to build up.

Your three-season room is enclosed so that you can spend time there in the cooler fall months, but that doesn’t mean it’s 100% weatherproof. You’ll still have some heating and cooling since it’s not insulated, so it’s not a bad idea to use exterior paint like this that’s designed to handle heating, cooling, and the moisture buildup that temperature change can cause. If the room was a converted porch, you’ve probably got a better chance of leaks, and exterior paint will hold up better to that, too.

If you’re looking for decorating ideas to spruce up the appearance of your three-season room, think about board and batten. It has a clean, crisp look that creates a calming environment. When you have guests over or throw a party, they’ll admire the crisp and neat look of your porch walls. Think about creative ways you can paint it to make it stand out, like painting the spaces between trim pieces in different colors or painting a mural of a bookshelf in between two trim pieces.

If your three-season room was originally a porch and was converted to a three-season room, you might still have the original siding on the house wall. If you don’t want to change that, you can use vinyl siding hooks like these to hang up your decorations without having to drill into or otherwise damage the siding. This way, you keep the siding intact and keep the look you want, but you can add a variety of hangings to decorate it.

Tassels are a neat little thing that looks old fashioned but can also fit a Bohemian theme. They’re great for porches because they have a feathery and natural look that blends into the outdoor environment and looks right on a porch. If you want your three-season room to feel more like a porch, you’ll want to make old fashioned and natural-looking decorations to create a porch-like atmosphere. You can use this tutorial by Jennifer Paglinawan on diys.com to make a hanging tassel decoration.

A three-season room isn’t insulated, so you’ll usually want to use outdoor furniture and other stuff for it, but there are some cases when you want to use indoor stuff instead. If you want to have gatherings in winter or even turn the room into a makeshift four-season room, you’ll want to get an indoor heater that won’t create harmful gasses like an outdoor heater might. You’ll also want it to look nice, so try an electric indoor fireplace like this. Make sure you’ve got at least one outlet to plug it into.

One common way to decorate any room without cluttering it up is an accent wall. It’s a great way to make the room look nice and cover a large area without losing wall space that you can use for practical hangings. For a three-season room, it’s neat because you can see it from the yard or from inside the room. Try making a board and batten accent wall using these directions by Brooke Jones on Hometalk, or get a couple gallons of paint and simply paint the wall.

If you want your three-season room to be old fashioned and have an outdoorsy or natural feel, there’s nothing more natural than yarn, but if you don’t know how to knit, what can you even do with yarn? Don’t worry; knitting isn’t the only yarn-related craft you can do to create a neat old fashioned or natural vibe. Try using this tutorial from Seeking Lavender Lane to make an easy-to-make yarn hanging that you can customize in the colors and patterns you like.

In some ways, three-season rooms are fancier and more comfortable porches. You can spend a lot of time in them, but they’re still as close to nature as you can get without leaving your home, so you’ll want some rustic and natural-looking decorations and furniture. They also make a great mudroom all year long, since you can spend time there, but you can also leave your boots outside to keep the inside of your house nice. Look for rustic mudroom decorations and furniture like this rustic coat rack.

Hammocks are fun decorations that you rarely see indoors, but there’s no reason they can only go in a yard. You can bring a hammock into your three-season room to make it feel like a part of your yard, particularly during the fall months when you can’t use the yard because it’s getting chilly and windy. You can even get a hammock chair like this so that you don’t take up a lot of space, but you get more freedom to swing around than you’d get with a porch swing.

Wind chimes are traditional porch decorations, but your three-season room is enclosed, so what’s the point of a wind chime? The wind won’t hit it, but wind chimes aren’t just about the noise they make. You can add a colorful glass or shell wind chime like this that will catch the light and make the area look more like a porch, even though it won’t catch much wind and make noise. You can even open the windows during the warmest months to get a little bit of that lovely chiming noise.

A three-season room is a type of porch, so you’ll probably want some porch decor that highlights all the things you can do with a three-season room but not a porch. An easy way to do this is to get a porch sign like this one from Amazon. This particular sign is great for bookworms, so if you spend a lot of time reading in your waterproof, dry, and comfortable three-season room, this sign is an exceptional way to invite people in and make it feel homey.

People forget about lights a lot when they’re trying to decorate, but they’re a major part of decorating an outdoor space. There’s a reason people like to use them for holiday decorations. If you’re relaxing in your three-season room at night, you might be reading a book and need a lot of light, but a lot of the time, you’ll want a soft and calming light. One way to do this is to get a light curtain like this that can be both a decoration and lighting.
