Thinking about a real tattoo sleeve: it continues up and over the shoulder smoothly without interruption; and so I decided a conventional set-in sleeve with the seam on the shoulder would truncate the print and end up looking kinda wrong. The best style for this look would be a raglan sleeve.
For which I did not have a pattern...
It's funny; a raglan sleeve, whilst a recognised "thing" in the sartorial world, is very poorly represented in the sewing pattern kingdom, don't you think? In terms of population: the almighty set-in sleeve is the over-ridingly dominant species in the gene pool, closely followed by the kimono sleeve and the humble raglan sleeve is verging on being an endangered species!
So I set out to make my own pattern. Luckily, I have a small raglan Tshirt from many years ago which has long since passed into Cassie's possession, so I temporarily repossessed it, and laid it down to trace around the sleeve, and then played around with my own self-drafted Tshirt pattern to fit in the new sleeve with a few minor sizing adjustments.
So now I have a raglan Tshirt pattern :)
The raglan sleeve is a very tall pattern piece compared to one's common-or-garden, set-in sleeve pattern piece, so it took up practically the entire Tshirt! But I tried to get in as much of the design as possible... and I love the wide and flattering boatneck-line. I preserved the lower hemlines of both the Tshirts intact to be the new Tshirt's sleeve and lower hemlines respectively.
My family have all voted this their favourite of my new Tshirts!
