There are some lovely ideas in here. It reminded me of doing the same thing after leaving a grim relationship.
You can find some great furniture bargains on Facebook marketplace ( our village has a ‘free’ page). A little coffee table or bookshelf can make all the difference.
Pictures on the walls by your girls is a lovely idea. Supermarkets do great plants in ceramic pots. Sainsburys also has nice faux arrangements. You can’t go wrong with a few fairy lights.
IKEA is great for super low cost lamps, throws and cushions. Nice frames for photos and pictures. A trip there and my little flat felt great. I still had the £75 pine table and chairs set 2 babies later!
IKEA is also a great spot for kitting out a kitchen. A big casserole pot and ladle is essential for homeliness. And lay the table ( when it comes) with a cloth. I still have the fabric I hemmed by hand for that job).
You can’t buy memories at IKEA, but I bet if you look around you’ll be amazed what you’ve got that you could make into something special. Photos to print onto canvas, pictures your girls have made, a tiny baby sock, old postcards and tickets to frame, baskets, bangles and hats to hang on the wall. I framed some wallpaper and birthday cards I liked, which looked super on a plain wall. I do also love a framed map.
Remember, you are on the right line creating a home for you and your girls. It’s not about the money you spend or an aspirational look. A home is a place to feel safe, warm and loved. Best of luck.
