Since the design method used for interlocking crochet is not standardised,  the answers listed pertain only to patterns created by Lynne Adriaanse.

Q: How do I know which is my A Color?

A: The A color is normally the color that creates the picture. Sometimes its the line that creates a line drawing effect & other times its the sets of solid stitches. The project can also contain both of these (line drawing + solid stitches)

Q: When is the A color used?

A: Each numbered row consists of 2 parts: an A Row & a B Row. The A color is used on ALL A rows and the B color is used on all B Rows

Q: What is the reason for the B (second) color?

A: The B color is what creates the background mesh of the technique

Q: Which color is crocheted first?

A: First crochet your A Color row and then the B Color row

Q: Do I cut my yarn after every row?

A: Unlike overlay mosaic crochet you DO NOT cut the yarn at the end of the row. Instead, you turn your work after every B row is completed

Q: How do I know where my B color should be at the start or end of a row?

A: This is normally indicated for you on the pattern. But the rule is: at the START of EVEN numbered rows (eg: 4A) the B color should be laying BEHIND the A color). At the START of UNEVEN numbered rows (eg: 5A) the B color should be laying INFRONT of the A color

Q: Which border is crocheted first?

A: The B color (inside) border is crocheted first.

Q: My B color is in the wrong position at the start of my new row. How do I fix this?

A: Check:

  1. How you ended the previous A Row (i.e with the correct stitch)


  1. Check that you have not inadvertently twisted the stitches around each other

Q: What is the best way to deal with a long foundation chain?

  • There are a few methods. I prefer to do a normal foundation chain and place a stitch marker in every 10 or 20 stitches so that its easier to keep count

Q: What yarn can I use for interlocking?

A: I prefer 100% mercerised cotton in a sport / 4ply / #2 weight but you may use whatever yarn you prefer or is available to you

Q: Does the weight of the yarn change the size of the project?

A: Yes it does. The thicker / heavier the yarn, the larger the project will be.

Q: What hook size is best to use?

A: It is best to use the hook size that is called for on the yarn label. However, each crocheter’s tension is different, so use what works for you.

Q: What crochet terminology is used for interlocking filet crochet patterns

A: To date, I have only seen patterns using US terminology but it’s always safe to check the pattern notes before starting

Q: Which crochet stitches are used in interlocking crochet?

A: The stitches used are Double Crochet and Chains.

Q: What are F stitches and B stitches?

A: The F and B stitches in interlocking crochet are not to be confused with a front post or back post stitches. F stitches are DC (Double crochets) worked facing you / towards you

B stitches are DC (double crochets) worked away from you / to the Back

Q: What are DCIF stitches and DCIB stitches?

A: This is definitely one that means something different for every designer.

 In my patterns, DCI stitches refer to a set of solid stitches (consecutive DC stitches worked with NO chains in between them.) The chain one is worked at the end of each set.

I.e DCIF 3 = 3dc, ch1

DCIF = Solid stitches to the FRONT (worked on uneven numbered rows) DCIB = Solid stitches to the BACK (worked on even numbered rows)

Q: What is the right side of the work?

A: The uneven numbered rows is the right side facing of the project.

Q: Do I need to know how to read the graph?

A: No, you do not. The pattern instructions are written out for you. The graph is included in order to give you a visual representation of the project
