I absolutely love the look of baker's twine, but haven't yet invested in a large spool. Instead, I make short lengths of improvised baker's twine as needed.
It's super simple - just use your sewing machine to zig zag along a length of twine or yarn. I use a wide and long zig zag stitch and pull the string from the back as I stitch.
Experiment with colors of thread and string and length of stitch. One of my favorites from last December was grey wool yarn with white thread on the bobbin and red thread through the needle. The possibilities are endless.
I love to wrap gifts almost as much as I like to make gifts. This package is one of my favorites - I made a bread/reusable produce bag out of a tea towel (Ikea - 49 cents!) with a homemade drawstring. I attached a little hand crocheted strawberry (I'll publish the pattern after the first of the year) as a hint to the content of the package (can anyone guess what's inside?).
Here's another fun and easy gift wrap - make a large envelope out of brown craft paper or a brown grocery bag using a large zig zag stitch on the sewing machine. Punch two holes up top and tie the envelope shut with custom twine (white thread on red crochet thread).
Happy wrapping! I've got some more twine to make and strawberries to crochet.
