You realise that the ironing board cover needs replacing.

One minute it seems OK and the next it has ripped to shreds.

This is the cover I made from a brand new cotton doona cover I bought from the op shop.  It was the first time I had made one and I was very pleased with the result.  You can read about it here.

I could never have told you how long an ironing board cover lasted but thanks to this blog I now know that this one has given 2.5 years of service.  I regard that as pretty reaonable as I do a fair bit of ironing.
