My sister gave me a very handy gadget for Christmas - The Slipper. It is a soleplate attachment made from a "durable space-age material" (looks like silicone to me), which makes ironing safe for every fabric. The non-stick material glides over all fabrics. I tried it on delicate fabrics using the highest setting on my iron and it works!

I couldn't find any mention of it on the web so if anyone comes across a website for these, I'd appreciate hearing about it.
