Overview of what it'll look like and what it does.
This is a 2 part guide. If you don't have an Android (boo-urns!) then you can still use Part 1 of this guide (what you're looking at now) to make a case for ANY phone -- sans NFC tags.
Make a cutting template out of paper. Grab your phone, a blank piece of paper, a ruler, and a pencil/pen.
Add 1cm to the top of the paper for the hem. Measure the thickness of your phone and add that measurement to an additional 1cm for the inseam stitching. The total was 2.5cm/1" for me.
Place your phone down on the piece of paper (aligning it with your previously made lines) and mark the right side and the bottom side onto the template paper.
Complete the lines for the tick marks you just made. Use the ruler to make sure the lines aren't crooked.
Using the measurements for the thickness of your phone, add an allowance at the bottom your slip case.
Add the inseam to the right side. (Remember that it was 1.5 cm or 1 inch for me.)
Cut it out.
Your template should now be perfect for your phone!
Uh oh. Spoke too soon. Looks like my folded over piece of paper is not long enough to actually match up!
That's okay, use some excess paper to extend what you've already got. Just lay it on top to get the measuements.
Here I already added a 1cm hem line to the extra paper and I am taping the piece to my current template.
Overview of finished template!
Use the template to cut out the outer layer fabric. I used grey felt here.
Fold the outer layer fabric in half and pin the inseams. Make sure the phone can still slide in!
If your fabric has a "right" and a "wrong" way, make sure that you fold the fabric with the right way facing each other because you're going to be sewing the sides and then flipping it inside out.
Moving onto the inside layer, this clip answers, "Why foam?" (I get cutoff at the end there but you'll see what I was going to say in the next step.)
Cut out the foam but exclude the hem and inseam allowances.
Double-check how well your phone and the foam fits into your outer case and re-pin for snugness if necessary. We'll then head over to the sewing machine.
Sew the inseam but start your stitch 1cm down from the top to allow for the hem to be folded down.
One side down! If you don't have a sewing machine you could do this by hand.
The previous step but in video format and on the other side.
Trim off the excess fabric in the inseam but don't get in too close to the stitch -- make sure there's a little bit of breathing room.
Flip it inside out.
Put the foam back in.
Ta da! It fits! Now for NFC tags... That's in Part 2 of this guide so check it out!! Just search for "NFC". Otherwise, use hand sewing to create a hem to tidy up the opening of the case.
