Hack the Ikea Kallax shelf to build a worktable with a huge surface, convenient craft storage and easy mobility by sandwiching three small storage units between a base with casters and a plywood top with hardwood edging.
Good idea to extend sleeves that are too short. Transform socks into wrist warmers. This is a simple, but very clever idea. If you can crochet and or knit, then there are lots of pretty edgings that you could use on these.
Couching is simply sewing a heavy thread in place with a finer thread. Its a retro technique, too, that was originally done by hand, but it works beautifully by machine as well. I use a zigzag stitch to secure the heavy thread in place.
