I was going to subtitle this tutorial If You Can Peel A Carrot You Can Carve a Miniature Rope Moulding. Many scale model and dollhouse details are easy to carve. The rope molding shown here is carved from a round wooden toothpick just to illustrate how simple it is to practise and create. If you can correctly angle a paring knife to peel a carrot, you can carve this molding. Once you have the technique down, you can carve it directly onto the edges of miniature furniture, bases for lamps, or a number of other miniature and full size projects. It is a useful molding trim for dolls house doors, scale picture frames, and cabinets, and can be easily carved for scales 1:24 and up by adjusting the size of the material you work on and the measured carving lines.
The molding shown here was carved using a curved #12 scalpel blade, but it is also fairly simple to carve with a sharp #11 or #28 (concave curve) hobby knife blade, or a pocket knife. The scalpel blades can usually be used in a range of carving and craft knives. If you are hesitant about carving in miniature, practise the cuts on a carrot, using a paring knife, then just reduce the scale!
Safety Note: Before you begin carving, make sure you are using safety eyewear and using appropriate hand protection for the items you are carving. (high friction carving tape for fingers or carving gloves) Do not carve with dull blades, and carve only when you are relaxed and attentive.
