FLEXIBILITY: Backpack or Notebook Cover Pattern

* * *

For this project I’ve used POLYESTER yarn because:

1. It’s strong and light-weight – my crochet backpack of the size 44 cm x 39 cm = 17.3’’ x 15.4’’ weights 300 grams = 10.6 oz only.

2. Polyester is highly resistant to ultraviolet, water, which makes it ideal for long-term active use in bags. Polyester fibers can withstand 12 months exposure to sunlight and still retain over 67% of their strength.

3. It’s the best wash-and-wear fiber, it has impressive stain-resistance, it’s quick drying and wrinkle resistant!

4. It remains one of the most inexpensive textile products in the world – these 300 grams of polyester cost me $4.70 = € 4.30 without shipping.

5. It’s highly resilient and resistant to stretching and shrinkage – it keeps shape of this bag well. By the way, when polyester is blended with wool, acetate, or rayon, the durability of the blended fabric improves. When blended with cotton, polyester improves the shrinkage, durability, and wrinkling profile of cotton. Essentially, anything made from cotton can also be made with polyester.

What are negative sides of Polyester?

1. It’s very important to wash it in lukewarm water otherwise it the stitches will be deformed.

2. Polyester garments are not very comfortable for summer as you will sweat a lot in them.

3. Polyester is the 2nd offender in terms of microfiber pollution after the acrylic. Unlike biodegradable fibers like wool, cotton, or silk, however, polyester does not naturally degrade in the environment. It is knot known how long polyester will remain in the ecosystem before it degrades.


So, it’s up to you what to make this beauty with. 🙂

I suggest to use any DK-weight = 3 = Light (USA) = 8 ply (UK) yarn.

How to achieve the gauge specified in the pattern

I get frustrated seeing that many crocheters could not choose suitable yarn – even if I state the yarn weight in American and British systems, state the amount of meters and yards per unit. This info is often disregarded .

So, last week I wrote this article on my blog and posted photos of two crochet jackets having the same stitches in front but made with different yarn to illustrate why choosing the right yarn is very important:

If this article helps somebody, I’d be very happy knowing that my efforts do not go in vain:)
