AboutHenry Babcock Expertise I learned needlepoint from my grandmother over 30 years ago. I can answer most questions on the subject. I know about producing needlepoint as well as cleaning, repairing and restoring.
The term "petit point" really refers to the size of the canvas mesh. Usually petit point refers to canvas that has a gauge of 18 holes per inch or higher. Larger gauges (16 holes per inch or less) are sometimes referred to as "gross point" or just regular needlepoint.
You should be able to find plenty of places online to buy kits with smaller gauge canvas. Try searching for "petit point kits" and finding retailers that sell kits in the higher gauges. You can also purchase blank smaller gauge canvas and use a counted chart to make a petit point piece.
