The idea behind this is that you can put nappies, wipes and a few bags in so you can grab everything together. If your changing bag is anything like mine it includes spare clothes, every kind of snack, drink and toy your child could possibly need whilst out! 
I find it easier to carry this under one arm and a wriggly child under the other instead of the whole bag!
How to make.
You will need two pieces of fabric and some bias tape.
To get the right amount of fabric for the width I grabbed a full pack of wipes and a couple of nappies. Layed them on my fabric and cut extra length around. The extra length is to allow for the wipes and when filled and also for a quarter inch seam allowance.
I realise this isn’t particularly helpful for beginner sewers so my measurements were:
- 13″ wide
- 20″ long
Do check before you cut! Different wipe brands are slightly different sizes.
To make sure you have the width right pin one side, place wipes inside and pin the other side with them inside. Fold down the top flap to check that fits too.
Unpin and turn the fabric right sides together, re-pin and sew a quarter inch around the edges, leaving a gap to turn right side out.
Lay the material out and fold the bottom up. This will be the inside edge so we are going to use bias tape to make it look nice and neat.
You can make your own (I do) or buy ready made. For this bias tape all you need is a strip of fabric 14″ long and 3″ wide. Fold it lengthways in half and press. Open, fold the sides in to the middle, press. Fold in half and press agsin
When it’s opened you should have three clear folded lines. Fold in the ends so the tape has neat edges and is the right size, line up the two edges and pin like in the picture above.
Once you have your bias tape pinned down I find it helpfull to use an air erasable pen and mark down the line you will be sewing every so often. Sew all the way along then fold over and hand stitch the other side.
I watched this video and it’s so clear I’ve been doing this way since the start!
Fold the bottom up, ensure its high enough to fit the nappies and wipes in. Pin around it. 
Sew around the edge a quarter inch, I did a little forward and back stitch over the flap for durability. 
I used Velcro spots to close the bag and glued them with craft glue to make sure they stay put. To get the right placement put the nappies and wipes in the bag and glue on the spots for the flap. I squashed them down under a book over night.
Fold the flap over and glue on the other spots. Put a piece of card inside the bag to stop it being glued to itself 😜
Done!!
A great baby shower gift!
