I love a sweater skirt and the casual vibe they give off. To make your own easy sweater skirt, start off with an old sweater… the bulkier the better!
Next, take a pair of fabric scissors (or really sharp regular ones) and cut your sweater straight across, right under the arms.
Take the top portion of the skirt, and cut a 1 – 1 1/2 inch slit along the seam. This will be your waist band.
Turn your skirt inside out and place a thin line of fabric glue along the entire top edge of the skirt, fold down, and press firmly along the glue line (I like to take a fat sharpie and press around, so my hands don’t get messy). Make sure you press firmly, instead of rubbing around. If you spread the glue around, you may not be able to insert a waist band.
Since fabric glue doesn’t hold up extraordinarily well, I like to go in once it dries and do a quick stitch along the bottom of the band. When you’re working with chunky knits, you don’t have to sew in a straight line at all.
You need to find something stretchy to use as a waist band like elastic. I like to use an old bandage skirt from Forever 21 as my waist band (for a variety of things). I got this skirt for like $5, wore it out once, and regretted it.
When your skirt’s finished, wear it wth everything.
