I hemmed in no time at all the two pairs of pants for my grandson. They were both done my machine. All that's left with the pants is the elastic waistband. I don't usually use one piece of elastic, but multiple, small rows. I have yet to purchase the elastic.
The coat assembly took a little longer. I first stay stitched around the curves of the jacket and the lining to keep the jacket from stretching in those areas. I added a white muslin interfacing on the fleece at the same time I stay stitched the jacket. I hand stitched the interfacing at the shoulder.
What took the most time was the blanket stitch around the edge of the jacket and sleeves. I used a top stitching black thread. To keep the edge as even as possible, I basted around the whole jacket 1/2 inch away in white thread. I inserted the needle and black thread in every other stitch. Here's the jacket with the basting removed. All that's left are the buttons and button holes.
