I make these Reusable & Absorbent Underpads for a little friend of mine occasionally, and thought it might be a project others could use as well, so today I'm sharing a tutorial.
These pads are very easy to sew and while I mostly make them for medical purposes, they can be used for a variety of things. Some ways to use them are changing pads, for learning to sleep in big kid undies, for incontinence, for home birth and postpartum/menstrual....many possibilities.
1 yard PUL or other waterproof fabric
1 yard cotton batting for absorbency
1 yard flannel
1 package bias tape or at least 3 yards of fold-over elastic for binding (this will be enough for a finished pad that measures approximately 24x36, so you may need to adjust based on the size of the pad you are sewing.)
Layer your fabrics with the batting sandwiched between your flannel and PUL. The flannel is going to be the fabric upright, so a print specific to your project might be fun. I typically sew for kids, so I like to use lots of playful and colorful prints.
Pin your layer and stitch with a 1/4"-1/2" seam all along the outer edge. I like to cut my PUL a bit larger in case there is any shifting during sewing.
Once layers are stitched together, trim neatly all around the edge to about a 1/4".
I think it is easier to apply bias tape and fold-over elastic to rounded corners, so I like to round the corners of my pads with any round object, and trim.
Now you are ready to apply either your bias tape or fold-over elastic to finish the edges.
I often like to sew my trim with one of my machine's zig zag stitches. This allows you to catch the underside of the trim more easily.
There you have it! So much softer, cuter and more personal than disposables. Before you know it, you'll have a nice bundle of these so there are plenty to use between wash days.
