I also love having time to do other things! This took a couple of hours even to take pictures. Then as it is my tradition, we had lots of fun in the outdoor photo session. I used for this a very special pair of pants {sentimental meaning} with an easy trick that also ends up revamping it.
How to Lengthen Pants That Are Too Short
Some pants are easier to revamp than others. When you don’t have enough hem to let down, you can lengthen your pants by adding a fabric cuff to the bottom.

Supplies:
- Pants
- A cute fabric of your choice
- Matching thread
- Fabric marker, pencil or chalk.

I found a fabric with details in light violet, which was perfect because the pants have those cute flowers in violet too. So it was a perfect match. Yayyy!

The Pants’ Cuff
1. The first thing is to measure the length of the cuff.
2. Put the pant on your girl and measure how much more length you need to add to the bottom of the pant leg.
3. If for example, you need 1,5 inches you add 1 more inch and then double it.
4. So it would be 1,5 + 1 = 2,5 x 2 = 5 inches.
5. Then measure the width of the pant leg at the hem level.
6. Double that measurement and add ยฝ inch seam allowance on each end.

7. With wrong sides together, fold each cuff along its width, bringing long edges together. Press, then open up again.
8. For the bottom fabric, Turn the long sides under ยฝ inch and then iron it.

9. Fold each of the cuff pieces in half along the length, bringing short edges and right sides together. Sew along the short edges with a 1 cm (1/2″) seam allowance to form 2 tubes. Press seams open.

10. Iron the seam allowance open like this.

11. Fold again putting together the hems like in the image below.

12. Now find the seam between the legs of your pants and match it with the extension seam, place the hem of the pants between both layers of the new fabric extension.

13. Pin in place.

14. The pant’s hem will be sandwiched between both sides of the fabric.

15. Turning the pants to the wrong side, fold the pants cuff up along the pressed fold. Pin in place, ensuring that the folded edge of the cuff extends about 0.5 cm (1/4″) past the seam joining the cuff to the pants. Then iron it.

16. From the right side of the pants, ‘stitch in the ditch’ of the join between the cuff and the pants, making sure that you catch the inner edge of the cuff in the underside of your stitches.

17. Fold the extension so it would hide the seam.


Cute Matching Pockets
1. Then cut a rectangle for the pocket.
2. The measurement will depend on the area of your pants.
3. Leave 1 inch on each side as seam allowance.
4. Fold ยฝ inch wrong side together, then iron it, fold again another ยฝ inch to enclose the raw edge, and iron it again.
5. Stitch one short side as the opening of the pocket and pin it in place.

There you have it! A new pair of pants!

I love how it turned out and my girl loves it too!

Now you have a pair of pants that will last a few more months… hopefully???

Crafting Tips
This technique is also a really nice way to add some interest or accent to a pair of plain pants. Even if the pants don’t need to be lengthened, sew exactly as above and turn up the cuffs so that when your child grows you can simply fold them down for extra length.
If the pants you are lengthening are jeans, you can use a different shade of denim fabric to make the cuffs.
You can make the cuff with cute ruffles instead of this technique. Or even creating different layerings of fabrics to create some crazy effect.
