This 25 page PDF pattern thoroughly examines and demonstrates how to adapt a already sewn bag into a nice bag for attaching to your own bike(s)! This pattern is the result of a year's time of testing and retesting many bags for safety, ease of sewing, and simply look like it was made for bike use rather than the other way around.
In the instructions, you will find 2 bags used as an demonstrator that were made for either 1. attaching directly onto the handlebars (very easy and quick to do), or 2. adapting a bag to a fixed support frame (i.e. Brompton's own one or even to a rear rack or the back of the saddle). I used many photographs and illustrations to document my steps in selecting the right bag, marking, then sewing it up.
Being a PDF pattern, only the instructions will be sent via email to the email address you wish to be sent to, or by default, your Artfire one. Supplies and other required items are not included in this sale (sold separately). I like to send the pattern out within 24 hours after payment received at my Paypal account, but do allow for possible technical difficulties outlined further on my Policy page.

Good quality polyester sewing thread
Tailor's flexible soft cloth/plastic Measuring Tape
