Unpicking your knitting from the bottom or the cast-on edge is one of the ways to shorten your pieces. So, yes, you can unpick knitting from the bottom. Follow this simple guide to know how to unpick knitting from the bottom: First, you need to decide on your project’s length. Measure the project and place a pin or a locking stitch marker to mark your desired length. – Undo the seams if your work has them. Do this step until you reach a spot a few rows above the marker. – If you plan to add a band at the bottom, you also need to measure the band’s length. Then, place another marker so you can easily see it. Make it your primary marker and remove the other marker to avoid confusion later. – But, if you plan to add length to your project, you need to mark its first row instead. Next, place your project on a flat surface, so your cast-on edge is at the top. But, you might need to turn your piece upside down if you worked from the bottom up. Take your scissors and snip the yarn in the marked row one stitch away from your work’s right side. Undo the yarn from the first stitches on your work’s right side. Then, take a knitting needle and pick up those stitches from back to front. Continue unraveling the yarn stitch by stitch and pick up the stitches until you have them all on your needle. a. If the unraveled yarn becomes too long to manage on your needle, you can cut it to make things easier for you. Remove the marker, then attach the working yarn to the yarn tail. – The yarn tail will be either at your work’s left or right side, depending on the row you cut through. – If the tail is at the right, you need to take another needle in your left hand. Then, slip all the stitches from your right needle to the left needle. – You can also slide the work to the other needle tip if you used a double-pointed or circular needle. Finally, finish off the project by adding a bottom band, binding it off, or making it longer.
