HELP with treble!

[Annapanna]

Hi!

My pattern tells me to "Ch 4, 3dctog over the 3 tr, ch 1, 1 dc in the ch sp at the beginning of the work, turn." My question is, what do they mean with dctog OVER the tr?

Hi, welcome to the 'ville!

When you do 3(any stitch) together you do this (I'll describe a treble, but this works the same for SC, DC, and so on: 

Make a treble in the first of the 3 stitches, except the last yarn over and pull-thru - you will have 2 loops on the hook.

Do the same in the second of the 3, you will have 3 loops on your hook.

Do the same for the last of the 3, you will now have 4 loops on your hook - yarn over and pull thru all 4 loops.

When you do a cluster (similar, except multiple stitch into 1 instead of spread out over more than 1 stitch, or a 'together' like this, you always end up with 1 more loop on your hook than stitches, before the final yarn over - just in case you get distracted and forget where you were (as I sometimes do when watching TV), or think you should have the same number of loops, it's a handy thing to remember.
