Triangle Pencil Case Tutorial

triangle-pencil-case-tutorial

Have to told you i’m addicted to making pencil cases at the moment? It could be because i find it very relaxing to colour in using glitter gel pens.

I made myself a new pencil case for all of my pens last week using the Kindle case tutorial and resizing it down slightly. It fits so many pens that i may have bought more of them…

I wanted to make some cute cases for friends and to sell in my store. These are so cute i needed to give you a tutorial!

Press all the pieces away from the zip.

At this point you can top stitch however it’s not needed if you press really well.

Ensure the zipper pull is in the middle of the case.

Place the lining pieces and exterior pieces right sides together. Face the teeth of the zip towards the lining, this is important for the zip to sit correctly.

How to match side seams

I used a metal zip, with metal zips it’s important to walk the sewing foot over the zip teeth, if you have a nylon zip, sew slow.

Sew each side of the case with a 1/2″ seam allowance.

Leave a turning hole on the bottom of the lining piece 3-4″ long.

create the flat bottom by nesting the corner seams and sew 1/2″ from the edge.

Do this for all 4 corners. You may need to reach through the turning hole to open the zip fully.

Pull the pencil case right side out through the turning hole.

Press and the stitch the hole closes with and edge stitch.
