Abbreviations:    

  • st: stitch    
  • sts: stitches    
  • nxt: next    
  • ea: each    
  • beg: beginning     
  • sl st: slip stitch    
  • ch: chain    
  • dc: double crochet    
  • *invslst: invisible slip stitch   
  • *CSDC: chainless starting double crochet

*This is a special stitch.  See instructions below to learn how to work this stitch.  Click here for a video tutorial on how to work the CSDC and Invslst, as well as how to change colors with this method.

Invslst: Remove hook from current loop.  Insert hook from back to front through the top of the CSDC from beg of round.  Place original loop back on hook.  Pull loop through the st from front to back.

CSDC: Pull loop on hook until it is slightly longer than a regular dc.  Holding the top of the loop still with your finger, yarn over with the loop on your hook (not the working yarn) 1 time.  Insert the hook into the specified st.  Yarn over, pull up a loop of yarn.  *Yarn over, pull through 2 loops on hook* 2 times.

 

 

 

 

 

In this pattern, you can change colors at the end of any round to make any stripe pattern you like.  I used 2 colors in my hat, with 2 rows per stripe in each color.

To Change Colors: When you have completed the invslst at the end of the round, yarn over and pull a loop of the new color yarn through the loop on your hook.  Pull on the old color yarn until the previous loop disappears.

 

 

 

 

To Carry the Unused Color Up the Inside of the Work: At the end of each round where you are not changing colors, twist the unused color yarn with the working yarn and continue crocheting with the current color working yarn.

 

 

 

 

 

Gauge: 10 double crochet stitches = 3” (7.6 cm); 6 double crochet rows = 3” (7.6 cm)

 

 

 

 

 

NOTE: When pattern says something like, “ *dc in nxt st, 2 dc in nxt st* 11 times around”, it does not mean to work the sequence between *and* once, then repeat it 11 times more.  It just means to work the sequence between *and* 11 times total.

      Hi Nicole! Round 4 is only worked once. I did show how to twist the yarn and change colors in between rows in the video, but round 4 was only shown once. Hope this helps! I’m so glad you are enjoying the invisible join method!
