Start by making some 16 patch blocks. (If you have never made a 16 patch block there are excellent instructions on how to make them here. ) You can make your blocks any size as long as they are all the same. In the example we are using 5" blocks but I have also made it in 3 and 4 before and they all look great. You will be able to get 2 Disappearing 9 patch blocks out of each 16 patch block.
Grab your first 16 patch block that you made in the last step. Lay it out on your mat. Don't worry to much about lining it up, it doesn't matter. Now, if you have a yard stick it will probally be easier to use. Unfortunately, I don't own one. Crazy, I know. If you don't have a yard stick use your long ruler and another ruler lined up together. Lay your ruler diagonally across your entire block. You want to try and make sure that your ruler is intersecting each of the corners. Make sure to really smooth your corners out, they will want to creep in on you :) Once you are all lined up, go ahead and cut along the diagonal.
Now don't move your fabric. Go ahead and pick up your rulers or yardstick and align them along the opposite diagonal. Once again, make sure to intersect all of your points and to smooth out your corners. Honestly, a lot of times your points will be all lined up and then you will find the edge doesn't line up. Most often it just needs to be smoothed out. Once you are all lined up go ahead and slice along the diagonal.
Now you can go ahead and pull your 4 parts apart. You will end up with 1 - 2 of these little scrap pieces hanging out either under your square or poking out. Go ahead and cut them off. This will help to reduce bulk making them easier to piece in future steps.
So out of each 16 Patch Block you will end up with 4 wonderful, adorable, easy to make, triangles :)
Continue this process until all of your 16 patch blocks have been cut. You will have a fun little pile of triangles.
Now, back to more random piecing fun!!! Go ahead and grab 2 triangles and line them up as follows. Once again, you are trying to keep it random so don't stress to much about what lines up where. Just try to avoid having the exact same blocks across from each other :)
Now it is on to sewing. Once again, sew a 1/4" seam along your pinned edge. Make sure to remove pins as you go and to double check your seams that they are laying flat by running your finger underneath the seam right before you sew across it. Continue to chain stitch all of your Disappearing 16 Patch Blocks.
Now, this step is not necessary but only takes a second and I like to do it to reduce bulk. Along the corners of the inner squares there will be a small triangle that is "hanging out". (The little red plaid one) I like to clip these out in all four of the corners. Once again, not necessary, it just reduces bulk.
Lastly, turn over your block over. You will have 4 little triangles sticking out from the center seam. Go ahead and clip them even with the block. Repeat for all 4 edges.
And there you have it. A stack of adorable Disappearing 16 Patch Block. So now what can you do with these cute little guys, the possibilities are endless!!
And for fun, here are some images of the finished quilt from the Quilt-A-Long. You can get all of the directions on how to make this quilt in the Quilt-a-Long link at the top of the page :)
