Crochet Pattern Notes
- This crochet pattern is written in US terms.
- All measurements given are unblocked.
- Note that measurements are given as exact as possible. But crochet tension & technique might give variations in the result, that changes from person to person.
- Read pattern instructions carefully before beginning to make sure you understand everything. It might save you hours frogging your work & crocheting it again!
- Make a swatch that measures at least 10 x 10 cm / 4 x 4 inches using the stitch the gauge is given for. If your swatch matches the gauge, you’re good to go. If the gauge is wrong, you might need to change your hook. Go up in crochet hook size if your stitches are smaller & go down in crochet hook size if your stitches are bigger. Learn more about testing gauge.
- Check yarn info if you want to find an alternative or test your yarn against the gauge. Learn more about substituting yarn.
- This pattern is written for 9 sizes, where the different sizes are given in parenthesis like this: XS (S) M (L) XL (2XL) 3XL (4XL) 5XL. If just one number is given, it applies to all sizes. I recommend that you highlight or circle the size you’re making before you begin to make the pattern easier to follow. Size adjustments are added under the heading “Sizes & Measurements”.
- At the end of each row, the stitch count is given in parenthesis.

Stitches You Will Need
Back Loop Single Crochet (BLsc)
Crochet single crochet stitches in the back loop instead of the whole stitch.
Techniques You Will Need
Crocheting in the Front and Back Loop
This means that you will not crochet through the whole stitch as usual. A typical stitch contains two loops. One in the front, nearest you, and another stitch in the back, furthest away from you. One is called the front loop (the one nearest you), the other one the back loop, the one furthest away from you.
These stitches are abbreviated with FL and BL in front of their regular abbreviation.
Mosaic Crochet
To crochet this pattern you will use the mosaic crochet technique, following these 3 simple rules:
- You will use color A & color B every other row.
- All single crochet stitches are worked in the back loop.
- All double crochet stitches (long double crochet/ Ldc) are worked 2 rounds below in the front loop & this front loop are always the same color as the one you’re working with.
