Hi I’m Mike I have a question my project said put a marker on the end of the row 24 & 25
There must be something in your pattern later on that tells you what to do with those marked rows. Do you have a mini stitch holder you can attach to the actual stitch rather than putting a round marker on the needle? I have some which are like mini safety pins and some others which are little spirals like a pigs tail which can be threaded through a single stitch.
If not, you can mark those 2 rows by adding a length of yarn through the last stitch of each row. A contrasting colour is helpful so that it’s easy to spot. Just put it through the last stitch (not too tight) and knot it so it doesn’t come loose.
Hope this helps
