Sewing supply companies such as DMC threads often provide free needle punch patterns on their websites; DMC's site, for example, includes a 20-page PDF booklet. Free needle punch patterns also appear on some folk art sites, and retailers' sites often have a few free patterns to get people started.
Needle punch embroidery, also known as punch needle embroidery, shares several techniques with rug hooking. This means that a lot of free patterns are available from general craft sites such as Needlepointers.com, and more can be converted from the many rug patterns that have accrued over the years. The craft is also the modern version of the traditional Russian Orthodox craft Igolochky, which means that traditional patterns are frequently made freely available by history enthusiasts and educational establishments to promote the ancient craft.
Commercial sites tend to offer mainly paid-for designs and patterns, but they often have one or two older designs available for free to showcase the work of their designers and encourage new crafters to use their products. The sites of sewing equipment suppliers also often have patterns available for download that are intended to be made using their products, though it is not usually difficult to adapt these to use generic materials.
