Tried of matching up sewing thread to the right bobbin, I made this wooden holder to end the search. Each rung has the same number of 1/4" thread pegs and 3/16" bobbin pegs just place your mating colors in the same order, now you know that the first peg on the left is the same for the bobbin side.
This holder measures 23 1/2" Wide 13 1/4" Tall folds down to just 3", opens like an A Fame or I provided hall hangs if a wall is next to your sewing machine.
Four rungs with 8 pegs per size, able to hold 32 spools, 32 bobbins. Pegs are not glued in just in case you break a peg making it easy for you to remove the broken base, I also provide extra pegs as backup.
As with all my units this is to show you the style do you need more or less pegs to hold your sewing needs, just let me know and a different size will be made.
