Three of my 7 grandkids are 7 years old and entering 2nd grade this year, two granddaughters and one grandson! I decided to make back-to-school outfits for them. For the grandson, I wanted a button-down shirt, one for warm weather and one for cooler days. I found a nice homespun cotton fabric for the long-sleeve shirt but nothing really "spoke" to me for the short-sleeve shirt.
I went to the local thrift shop and looked at the XL men's shirts. I found a couple with suitable plaids and got them for under $5 each. Long-sleeved is best - more fabric!
When using a ready-made shirt as a fabric source, you have a couple advantages but also need to be aware of a couple adjustments. As the hem and front placket are already done for you, you can skip the front facing and hemming options. If matching a curved hem, as I did, the back is cut as two pieces. Be sure to add a seam allowance in the center back (I added 1/2") - along the fold line. With a small plaid this seam will not be visible. Be sure to reverse the pattern for the second 1/2 back piece.
Side Note: As an offshoot of my heirloom sewing, where all seams are finished in some fashion, I try to enclose ALL seams of my projects. Especially on children clothes. I believe this is a modified French seam as it is done on the inside. I trim one seam allowance down to a scant 1/4". I then turn the other seam allowance over and under, enclosing the raw edge. This is then top-stitched. FYI This is the long-sleeved shirt I made with the homespun cotton.
When placing the front pattern piece, slide the pattern out the width of the seam allowance along the center front edge. Since the front placket is done already, you won't be stitching that seam. There are also no buttonholes to make or buttons to sew on!
Cut both sleeves off at the armhole seam and lay wrong sides together.
Once the pieces are cut out, this is all that remains of the original shirt! The larger pieces went into my scrap box. I also cut off the remaining buttons for my 'button box'.
The last adjustment is to make sure the collar goes ALL the way to the edge of the front placket. Without a front facing, you need to make sure the collar seam is covered. Either select a pattern with this feature or adjust the collar to fit.
Not bad for around $5 and a few hours of sewing!
