Intermediate is probably the first time many boys have had to wear a uniform for PE, That means carying a whole kit of shoes, socks, shorts and shirt to school at least twice a week. One of the first things we sew in Year 7 is a simple drawstring bag to hold PE gear. We use parka nylon - it comes in bright colours, it's easily washable and it's cheap.
There are plenty of drawstring bag tutorials around but we make this version for one reason - lots of practice sewing long straight lines. Start with a piece of fabric 40cm wide and 100cm long and hem all 4 sides. This is where the practice comes in...
Fold both short ends 8cm to the inside and mark 2 casing lines. The first casing line is 3cm from the top edge and the second is 5 cm from the top edge. Sew along all four of the casing lines you have marked.
