In golf-practice configuration, the hollow member and the insert member cross each other at 90 degrees and are adjustable relative to each other for different ball placement. In a storage configuration, the insert member is removed from the connector and slid and latched into an interior space of the hollow member. The hollow member and the insert member are preferably tubular so that the storage configuration is generally a tube-within-a-tube. The preferred connector is near the intersection of the hollow member and the insert member but does not require any structure to be between the hollow member and the insert member at or near the place where they cross each other, resulting in a low profile guide. Preferably, only a small portion of the connector contacts the practice mat or ground, resulting in minimal resistance to movement on the mat or ground. Multiple, sharply-pointed pegs may temporarily fix the guide to a mat, and may be connected to the hollow member and/or the insert member for storage of the entire device as a single, compact unit. ## Claims ### Claim 1 A golf stance guide for placement on a mat or ground, the guide comprising: an elongated first marker for placement on an imaginary target line near a golfer's feet;
