Invisible Decrease (INVDEC) Tutorial Video
This invisible decrease technique is for Single Crochet amigurumi. It makes a tidy, virtually unidentifiable stitch that pulls two stitches from the previous row into one stitch on the current row. Keeping in mind that this technique only works when you single crochet in both loops and work with the right side facing outward. The technique detailed below is done from the right handed perspective.
First the video
Step by Step InstructionsStep 1 Aim your hook in a downward direction then upward to pick up the front loop (loop that is on the outside or right side of your piece) on your hook. This can be kind of an awkward motion and you may need to slide your hook back to go down and then push it through a bit to go up. Step 2 Now with that loop you just picked up on your hook, slide your hook back so you can go down and then up to pick up the front loop of the next stitch in the same way. Step 3 Now you have 3 loops on your hook, the 1st and 2nd loops are the front loops of the two stitches you will be decreasing into one, and the one at the back of the hook, is what you started with. Step 4 Now yarn over and pull through the 1st and 2nd loop on your hook only. Do not pull through that third loop you started off with. Step 5 You will now have 2 loops on your hook, the yarn over that you just pulled through, and the one you started off with. Step 6 Now yarn over again and pull through both of the loops on your hook to complete the invisible decrease. Work this last step tightly and give your working yarn a good tug to minimize gaps as much as possible. All done! Two stitches from the previous row/round are now worked into one stitch which is tidy, not lumpy or weird looking.
If you are left handed or ambidextrous, and these instructions aren’t doing it for you, have a look at this video from Roxycraft, which should be a better point of reference as she is left handed so her demo will likely look more intuitive.
