We did something a bit different for our daughter's room and it turned out really sweet — we printed big letter outlines for her name, coloured them in together and mounted them on the wall above her cot. It cost almost nothing and felt much more personal than the shop-bought letters. The outlines we used were from https://eduimprime.com/moldes-de-letras-para-imprimir-gratis-en-pdf-a4/ — the page is in Spanish, but the letter shapes are the same in any language and you just print them at A4. She is a little older now and still uses the same sheets to practise tracing her letters, so they have lasted well beyond the nursery stage.
