Our collection

(our bed) King size sheets: 3 sets of 1000 count, 2 sets that are home-made and that I'm trying to 'wear out'
(spares) 3 sets queens size
(DD's bed) Double: 3 sets
(boy's beds) Single sheets about 10 sets because we inherited MILs good quality linen from the 1950's

Towels: Approx 20. Half are ex-hotel and given by a friend, good quality but on their way out. Will probably only replace with about 5 new ones so that makes 3 per person. When you factor in about 4 pool/beach towels then that means there is enough for emergencies.

The things that take up space in our linen cupboard are all the miscellaneous table-clothes (so many different sizes), bath mats, hand towels, cushion covers, pillow cases, doilies (love my cross-stitch collection) and other multi-purpose bits of fabric.

We have a quilt cover for each season for our bed... heavy damask for winter, medium weights for Spring/Autumn, and a light weight one for Summer. The kids have 2 doona covers each... so that's a total of 10 for our family of 5. I'm ok with that.
