you can make your fabric cutting machine[cutting machine?:CUTCNC sample maker cutting machine] entirely from scratch. A standard sheet of plywood, 4 feet by 8 feet, would make a good-sized table top, giving you plenty of room to spread out the cloth and work with patterns. If 4 feet by 8 feet is too large for your space, you can cut the plywood to make the table smaller, say 4 feet by 6 feet or 4 feet by 4 feet. Use 4 by 4 posts to make the legs, cutting them so your fabric cutting machine will stand 36 inches tall and making sure that they are measured evenly, or else the fabirc cutting machine will wobble.
Since you'll cover the plywood with cork and then paper[paper?:paper sample maker cutting machine], just as you would if modifying an existing fabric cutting machine , you don't have to sand and finish your homemade table. A coat of paint or wood sealant before applying the cork top would still be a good idea to protect and prolong the life of the wood.
