This is a simple project, perfect for recycling yarn and food packaging. It's a knitterly way to dress up a simple vase or pencil cup. Try this pattern or use leftover swatches or orphan afghan squares to make a cover.
The sample was knitted using a small amount of leftover Red Heart Super Saver yarn and US size 8 needles (5mm) and was fitted over a Ball 12 ounce Quilted Crystal jelly jar. Any worsted weight yarn will do. Try jars from jam or jelly, pickles, olives etc. or containers from frozen fruit juice concentrate. Just about any small cylindrical package will work, including tin cans.
Cast on 30 stitches.
Work 6 rows of garter stitch (knit every row).
Rows 7-10: *Knit 3, purl 3*; repeat from * to * across the row.
Rows 11-14: *Purl 3, knit 3*; repeat from * to * across the row.
Continue working this checkerboard pattern 4 more times; 46 rows completed.
Work 6 rows of garter stitch and bind off.
You will have a somewhat square piece of knitting. Exact size is not important, it will stretch and is very forgiving. Sew the sides together to make a tube with garter stitch at the top and bottom.
Slip finished cover over your chosen container and fold top down to form a cuff to make it fit.
