Here is a brief description of the process:
Go to a hardware store (I had hubby buy this at Lowe's) and buy clear plastic tubing in the plumbing section. The outside of the tube is 3/4" while the inside is 1/2". Note: If you send your husband to buy this, he might be a little skeptical so be ready to show him a picture so he will get on board.
In her tutorial, she uses an exacto knife to cut hers but since we don't have one, I had to use a box cutter. Either way, be careful of your fingers. I had a couple of close calls.
Next, I cut slices off one end of my tubing that would fit inside of my bobbins. She goes into more detail on her blog but here is one of mine:
And here it is covering my bobbin.....
Don't they look all neat and organized now?
If you are local to me, I have extra tubing (you get a lot of it for about $6) so I would be happy to share. Just let me know and I will hold some for you!
