Making simple no-sew pillows is quite simply easy as pie and has become one of my favorite pastimes....that I do in the present... a lot. I always seem to have clothing that no longer fits or has been 'injured' in some way, most likely a DIY project involving paint, fabric dye or cement... and turning those clothing remnants into pillows is a great way to get yourself a one of a kind pillow that is in a style you very likely love, you know, since you formerly wore the thing. It costs you no more than the fabric glue and perhaps a pillow insert if you don't already have on hand a shabby pillow you are also tired of and that could use an update.
If you are working with fabric you purchase, this process couldn't be more easy... simply cut your fabric into 2 equally sized squares approximately 1" larger than your pillow insert, place the 'right' sides in (facing each other), and run a line of glue in between your squares along 3 of the sides, let it dry for a few minutes, turn right side out, insert pillow, and carefully glue the last side by running a thin line of glue along one top edge and gently laying the other bottom edge over the line of glue. This is sort of like folding the top down on an envelope, only teeny tiny and much more permanent.
See how easy it is... I gave you the whole run down in 1 long run on sentence! Yay! Down below I will show you how I do this when I am working with a shirt or tank top, which seems to be the most common form my pillows come in these days.
