It suits (rather too large - but was so in the product description seen - better than too small ;-))
The attachment shall be made only with two people. One holds, the other pulls like mad to the cords, so that the reference to contract around the board and spanned. I always had a concern whether holding the strings, because you have to pull extremely strak. They stopped. I hope it works well again, if you have to remove the reference to wash and wants to refit.
The reference then sits pretty neat on the ironing board, however, is the narrow end really a lot of material left and accumulates under the ironing board. A few small wrinkles it therefore was already at the edges. I pulled taut with tension straps ("ironing table reference Spanner") - so it sits a little better.
Goofy are now long dangling cords that you now can not cut off if you have the intention to settle the terms again and re-install ...
