Teddy Bear Jacket, Debbie Bliss

I’m having problems with the back. After completing the decrease row I trie to do row 1 of the pattern. I keep ending up with 6 extra stitches on the right hand needle. When I counted the pattern stitches it adds up to 100 and not 106. Help! please

Hi and welcome!
You’re probably going to have to shift the start of the row because of the decreased sts. You won’t be able to start the pattern stitches as previously but you do want to maintain the over all look of the pattern blocks.
Figure out how many sts you’ve decreased and then where you should start the pattern row.
Is this the pattern?

If so, check the errata. They don’t seem to apply but may help later on in the jacket. Such a sweet pattern.
