Ironing Board Topper
Have had one for years (custom made via directions from the Internet), and wouldn't be without it. Though mine now rests across two construction worker "saw horses" for better stability.
My ironing table is about 6'x4', and has have often posted, can do ironing, especially of large flatwork quite easily and often faster with better results than any of my rotary ironers.
By the way, the idea for such a table, being the quilt show thing or mine, is not knew. Long before there were ironing boards, housewives, laundresses, and anyone else who had ironing to do did so on tables. Laundries often had several rows of long wood tables where ironing was done. Homes would likely use the kitchen table, which in some houses could also be the same long table. All one did is cover the thing with several layers of blankets or outing flannel, and then a clean white sheet.
Every single one of my vintage French laundry/housekeeping manuals shows ironing on a table, even items such as shirts, pants, dresses, chemises, etc. Today when shirt laundries hand iron shirts, most do it on flat tables, but they normally are the modern vacuum tables, and the iron is a commercial steam boiler/generator iron, or gravity feed steam iron.
IMHO ironing shirts flat on a table takes some getting used to, and tends to make creases. Also shirts with fancy backs are very hard to get flat from the inside, which is where they are ironed when one does them flat. If you want to see a show, stand in front of a local dry cleaner or place that does "hand pressed" shirts. Those pressers can whip through a shirt in about four minutes.
