A door. A cheap door. Works wonderfully for a large cutting surface.
For 24 bucks a hollow core door is a quick fix. (get the one without the predrilled hole for a doorknob). Put it over an existing small table or sawhorses and you have a really long and large surface to work on. Throw on some cutting mats and now you are cooking. Takes hardly any space to store when not in use.
Don't look at the mess, look at the table! This is my studio with our grumpy elf supervisor doing a selfie. Three doors on tables. Cheapest workroom ever.
Home Improvement Centers are also terrific places to shop for measuring tools. Much less expensive than sewing centers.
Invaluable when cutting out. I use mine constantly, it makes a great edge to cut against with a rotary cutter.
Once you have your door, and measuring tools, pick up some cheap clamps to help secure your rulers for cutting out those long piece of fabric on the straight.
Only 99 cents. Get a few. Use them to clamp down the metal ruler, it keeps it secure while you use the straight edge for marking or cutting.
And just when you think you are all done shopping at the orange or blue monster, hit the Laser Aisle and find a cheap laser level. It shoots a straight line. Priceless, ok, it has a price, cheap at 15.97.
Need to cut out some buttonholes? The Hardware Aisle is the place for you. Wood chisels are the way to go.
They often come in sets with a variety of sizes. Use on a cutting mat, and you will get perfect holes every time.
Not 18th century, not pretty or pink, but cheap, practical tools that can save you time and money.
