Hi Mason,
I use
the end caps to: reserve stitches on the shortest Options cable, making it a longer length 'stitch holder' than the other types of short 4" stitch holders.
I use
the end caps for various tasks, eg. knitting with sz 8's, each screwed onto their own 24" cable...with an end cap at each end.
I purchased 4 additional 24" cables, that come in a pack of 2. Very inexpensive. I find it most useful to have 6 of the 24" cables.
I also purchased extra 'pages' for my Options binder, which I just love!
Don't you think the Options binder is just HANDSOME looking!!??
I also purchased extra needle tips for my most commonly used sizes. Very inexpensive.
WHERE WAS KINITPICKS OPTIONS 5 years ago when I started investing in every size of ADDI in every length????

Man o man...KPO's are such a DEAL!!!!!
I am still toying with the idea of ordering the KIP knitting bag set! I love the fabric. Very handsome.
