A method of making an article of footwear, comprising: knitting a knitted textile element of unitary warp knit construction having a first knit layer, a second knit layer that overlays the first knit layer and is continuous with the first knit layer along a common edge of a common opening in the first knit layer and the second knit layer, the common edge of the common opening extending in a direction of knitting process, a first interlayer knit stitch line that interconnects the first knit layer and the second knit layer, the common edge of the common opening and the first interlayer knit stitch line collectively defining an outline of a first knitted component portion of a knitted component, the first knitted component portion being configured to form a seamless bootie, and a second knitted component portion of the knitted component that is seamlessly connected to the first knitted component portion by a first continuous portion of the first knit layer adjacent the common opening and a second continuous portion of the second knit layer adjacent the common opening, a second interlayer knit stitch line that interconnects the first knit layer and the second knit layer at a location spaced apart from the first continuous portion of the first knit layer and the second continuous portion of the second knit layer, the second interlayer knit stitch line defining an outline of the second knitted component portion, and the first knitted component portion and the second knitted component portion collectively forming the knitted component; removing the knitted component from the knitted textile element; and folding the second knitted component portion into an internal pocket formed between the first knit layer and the second knit layer of the first knitted component portion. knitting a knitted textile element of unitary warp knit construction having a first knit layer, a second knit layer that overlays the first knit layer and is continuous with the first knit layer along a common edge of a common opening in the first knit layer and the second knit layer, the common edge of the common opening extending in a direction of knitting process, a first interlayer knit stitch line that interconnects the first knit layer and the second knit layer, the common edge of the common opening and the first interlayer knit stitch line collectively defining an outline of a first knitted component portion of a knitted component, the first knitted component portion being configured to form a seamless bootie, and a second knitted component portion of the knitted component that is seamlessly connected to the first knitted component portion by a first continuous portion of the first knit layer adjacent the common opening and a second continuous portion of the second knit layer adjacent the common opening, a second interlayer knit stitch line that interconnects the first knit layer and the second knit layer at a location spaced apart from the first continuous portion of the first knit layer and the second continuous portion of the second knit layer, the second interlayer knit stitch line defining an outline of the second knitted component portion, and the first knitted component portion and the second knitted component portion collectively forming the knitted component; a first knit layer, a second knit layer that overlays the first knit layer and is continuous with the first knit layer along a common edge of a common opening in the first knit layer and the second knit layer, the common edge of the common opening extending in a direction of knitting process, a first interlayer knit stitch line that interconnects the first knit layer and the second knit layer, the common edge of the common opening and the first interlayer knit stitch line collectively defining an outline of a first knitted component portion of a knitted component, the first knitted component portion being configured to form a seamless bootie, and a second knitted component portion of the knitted component that is seamlessly connected to the first knitted component portion by a first continuous portion of the first knit layer adjacent the common opening and a second continuous portion of the second knit layer adjacent the common opening, a second interlayer knit stitch line that interconnects the first knit layer and the second knit layer at a location spaced apart from the first continuous portion of the first knit layer and the second continuous portion of the second knit layer, the second interlayer knit stitch line defining an outline of the second knitted component portion, and the first knitted component portion and the second knitted component portion collectively forming the knitted component; removing the knitted component from the knitted textile element; and folding the second knitted component portion into an internal pocket formed between the first knit layer and the second knit layer of the first knitted component portion.
