You can make rya knots with using only fingers when you make a rug in a loom. Rya knots can be made also with a needle when you sew a rug on a basecloth. In both cases the pile will be the same.
Sewing a rug is simple: all you need are basecloth, yarn and a big, blunt point needle.
UTENSILS
BASE CLOTH
You can use jute, gunny, or other firm, open weave cloth. You must remove some single threads where the pile row will be to make the sewing easier. Also canvas (aida) can be used. Then the thread removal is not needed.
Can you sew a rug on a metal net?
You can also ask: Why not...?
If the pile covers thickly all the basecloth the colour can be whatever. In so called semi-rug the pile covers only some areas in patterns and then also the colour of basecloth can be seen.
PILE THREADS
If you want to respect traditions use strong twisted woolen yarn. Also special pile threads are available.
Modern wall rug is no disposed to wearing and therefore it can be made from any kind of threads.
NEEDLE
The best needle is probably a real rug needle. It is big, it has large needle eye and blunt point. At least the needle should have those qualities. Large needle eye makes it possible to have many yarns simultaneously, same or different colours.
Tip: You can work faster if you have several needles with different pile combinations already waiting.
WHAT ELSE IS NEEDED?
design
chart and combinations of pile threads that will be used
pile splint
pile splint, for example a firm strip of cardboard ruler (to make pile of same lenght)
scissors, tape measure
WORKING
Oversew the base cloth. Leave a plenty of working spare on sides. You can draw your design on a base cloth, at least the main lines. You can also draw a precise grid design. Choose your own method.
Sew the pile in rows with the design. Start from the bottom. Study the sewing technique from images. Cut the links while working or in the en of sewing.
