Today I am making pillow inserts from leftover blocks. I have plenty of blocks leftover from swaps so I am making pillow inserts for my son's girlfriend. In this case I am actually including the pillow . Usually the average pillow form is 17x17 or 18x18 so I make the insert one of the 2 sizes. If you are shipping the gift overseas, it is less expensive to make the pillow inserts. Now pillow inserts have really become costly lately. So what I do is wait for Joann's to have them at 50% off , or I go to habitat or goodwill, buy a pillow in very good condition, cover it in a basic white or off white fabric and then make the insert for it. Since it will be a decorative pillow, it usually will not get much use. Now if you want to be creative, you can include some extra inserts so they can be switched out. Again, since these blocks are pre-made and measure 12x12, I just added a border and a back so I was able to make several at a time.Go ahead, make some pillows and share the picture for inspiration.
