This is what I've done to a sweater that just didn't do it for me anymore:
I wanted to make a mini skirt warm enough to wear in those cold months to come. I measured how long I wanted it to be then cut.
I finished the raw edge with a zigzag stitch to prevent it from fraying. I then measured my waist and cut the right amount of thick black elastic. I joined the edges and stitched to create a band.
I then pinned the skirt onto the elastic band and stitched with a zigzag stitched around, I did it twice to make it super strong. I used zigzag stitch as it is much stronger and suitable for a stretchy fabric which it was.
In colder months I really love to wear arm warmers and I I have them in various colours, most of them made from sleeves of old sweaters and this is what I've done with the sleeves here too.
Just need to make a casing and insert a thin piece of elastic so that my arm warmers will stay in place when I wear them^_^
What about you, do you tend to keep your unworn clothes for years and years promising yourself that you would wear them again..next summer, this fall..? Or do you recycle them like I now do? I would love to see what you come up with.
