I thought I'd share a recent purchase with you (I follow the one in, one out rule when buying things for my home!) to give an example of how making your home feel welcoming doesn't necessarily need to be about buying expensive items.
I bought this 'Love' sign online for
£1.99, and the vase was a gift from a relative. I've seen similar ones for sale at low prices in charity shops/thrift stores. The rose is from a rose bush that I have growing on my window sill. You could replicate it with a silk flower to be even thriftier - they can be purchased pretty cheaply. Arranged together, they help create a warm and cosy feel to my lounge.
