I bought these 'on spec' when I replaced my ironing board cover, thinking that I might need them, and I'm so glad I did! Whilst the cover itself is great, one of the fasteners was in completely the wrong place so I couldn't use it. Enter the clips! I have the very small one anchoring the cover at the end of the ironing board, and two more at the other end, holding the cover diagonally (I have a strange ironing board!). The last one I use to replace the redundnat cover fastener, and this works really well. I am very pleased with them, and they are great value for the price.
