You can use any of the Knifty Knitter long looms, or rectangle loom, to create ribbed knit. You can also create ribbed knit with a round loom, but the method is different.
Secure yarn to the anchor peg.
E-wrap the first bottom peg.
Pull yarn to peg on opposite side of the loom just above it and E-wrap.
E-wrap the peg directly next to it.
Repeat steps 3 and 4 until the loom is fully wrapped.
Turn at the last peg and wrap in reverse. The path of the yarn should follow the previous path of the yarn identically.
The secret to knitting a flat panel on either type of loom is to turn and wrap back to the starting peg, rather than in a circular motion around the loom.
Secure the yarn to the anchor peg.
E-Wrap 10 pegs.
Turn at the last peg and wrap back to the beginning peg. (Each peg will be ewrapped 2 times.)
Knit off (lift bottom loop over the top loop.)
Wrap each peg once more and knit off again repeating until the knit is the desired length.
