ive managed a large cot quilt on my ironing board--i spread a sheet on the lounge floor--put the ironing board in the middle--mark the middle of all layers +the middle of the ironing board --start in the middle work outwards both layers smoothed down as you go ---505 washed out of the sheet a little on the legs wiped off easily--i prefere outside but it was windy for 4 days straight---
