How to crochet a T-shirt-yarn bag with an oval base
The oval base is one of the most commonly used bases for T-shirt yarn bags when you want a balanced, practical shape with plenty of capacity. It is especially common in tote, shopper, and medium-sized everyday bags.
In this article, I explain how to crochet a T-shirt yarn bag with an oval base step by step, showing where to make increases, how to maintain the shape, and how to build the sides without distortion.
When to choose an oval base
An oval base is an excellent option if you are looking for:
- A stable bag without pronounced corners
- More capacity than a round base
- A shape that is comfortable for everyday use
- A visually balanced design
This is a very versatile base, halfway between a rectangular and a round one. For an overview of all the options, see the complete guide to crocheting T-shirt yarn bags.
Recommended materials
- Medium- or thick-weight T-shirt yarn
- Crochet hook suitable for T-shirt yarn (8–10 mm)
- Stitch marker
- Scissors
With oval bases, it is important to maintain consistent tension so that the sides do not ripple.
How to start an oval base
The oval base is worked from a central chain, with stitches made along both sides.
Round 1
Chain the desired length for the bag base. Work single crochet stitches along the chain.
In the last stitch, work 3 single crochet stitches to turn and continue along the other side of the chain.
Round 2
Work single crochet stitches along the straight side (skipping the first one, which already has 3 single crochet stitches). At the other end, also make the increases to maintain the curved shape, working 3 single crochet stitches into the last chain.
Next rounds
Continue crocheting in the round, increasing only in the curved areas (at the ends) while keeping single crochet stitches along the straight sides.
Where to make increases on an oval base
As you can see in the diagram, the key to making a good oval base lies in the increases.
- Along the long sides: no increases
- At the short ends: progressive increases
If you make too many increases, the base will ripple. If you make too few, it will curve into a bowl shape.
The base should lie flat when placed on the table.
How to build up the sides of the bag
Once the oval base reaches the desired size, stop increasing altogether.
Work one round through the back loop only (BLO) or through the entire stitch, without increases, to define the angle between the base and the sides.
From there, continue crocheting in a spiral until you reach the desired height.
What bag shape can be achieved with an oval base
Depending on the height, you can create:
- Low basket-style bags
- Structured tote bags
- Medium everyday bags
The oval base distributes weight very well and is comfortable to carry.
Recommended handles
These work especially well with bags featuring an oval base:
- Short tote-style handles
- Integrated crocheted handles
- Separate handles sewn on or attached with rings
If the bag will carry weight, it is important to reinforce the handle area properly.
Common mistakes when crocheting an oval base
- Not following the increase zones
- Increasing along the long sides as well
- Not using a round marker
- Building up the sides too soon
Conclusion
Crocheting a t-shirt yarn bag with an oval base is a very practical and rewarding technique, perfect for functional, well-balanced bags.
If you already have a rectangular or round base mastered, an oval one is the logical next step. And if you want to keep learning, you can return to the complete guide to shapes for crocheting bags.
