Sorry for not uploading any messages for the last month... I guess selling of everything you had for the childhood of your kid is taking that long!
But I did manage to do some refashions and one of them is this shirt my husband loves to wear. He has done so for 1 year and it was noticeable in the collar..
I took my seamripper and removed the collar, ironed it and zigzagged it and put it back on the shirt only front side on the back.
It turned out great. Now he wears his favorite shirt again without worrying about showing some sweat!
