Here's what I did. I took an old pillowcase that I liked and measured the dimensions. Mine measured 38" x 30". I opted to add a 4" contrast hem, so the dimensions I cut for the body of the pillowcase were 39" x 27" which included seam allowances of 1/2". The contrasting hem was cut to 9" x 39" which also included seam allowances. I cut these so that only one of the long edges of the pillowcase had a seam - it was just easier.
From here, all you have to do is sew up the bottom edge and side seam and seam finish them off. If you've don't have a serger, a french seam would be very easy to do.
For the contrast hem, I stitched the short ends together first and folded the long edges wrong sides together. Stitch to the raw edge of the pillowcase with right sides together, finish the seam and voila! Done!
I added a triple stitch to the top to hold the contrast hem seam in place. You could do some fun stitches that you never use or keep it simple. I opted for a quilting cotton I had in my stash, which is an easy natural, fun and colorful choice. Seriously, these are so easy and look how exciting they are - something you definitely aren't going to pick up at a department store!
Additionally, these are easy enough to change up a little too and who said you only had to use quilting cotton? I made this gorgeous set for my mom from some silk jacquard with a silk satin contrast hem and then for my darling little nieces, I went wild with prints, added a ruffle edge and some contrasting trim. All the fabrics were from stash and the ones for my nieces were scrap fabric! The design elements are all up to you and how personal/economical/time consuming you want to make them.
The more I think about it, the more I would love to receive a gift like this. So personal and functional - both things that I love! So if you're in the hustle and bustle and are wondering what in the world you're going to do for gifts this year, consider pillowcases! Enjoy friends!
