Short Sleeves to Long!


Let’s face it, Winter is raring and ready to go!  Here in northern Utah, we went from temperatures in the high 80s to low 50’s (F), in a matter of days! Sadly, I just went school clothes shopping and stocked up on warmer weather clothing.  To solve this, I’m taking the frugal route – all of those brand new short sleeve t-shirts are going to be magically transformed into long sleeved ones. Okay, not magically but it’s so easy to do, it might as well be magic!DIY Convert Short Sleeves to Long Sleeves for Winter

All that is needed is knit fabric. The amount varies depending on size but for each of Ivy’s size 6 t-shirts, I used a piece of  20″ x 16.5″ knit for the sleeves and cuff.

DIY Convert Short Sleeve Shirts to Long Sleeve for WinterStart by measuring the sleeve opening of the shirt. Ivy’s sleeve measured 5 inches so I knew I’d need to double that to go around the front and back of the sleeve. I measured Ivy’s arm from where her sleeve would start to her wrist and it was 12.5″.

Easy! Convert Short Sleeve into Long Sleeve for WinterI cut each sleeve 10″ wide x 12.5″ long plus I cut a long 4″ wide strip for the cuffs. Alternately, you could skip the cuff and just hem the bottom of the sleeve but I prefer finishing the bottom sleeve with a cuff. It’s easy to do and makes a nice finish.

    That is such a great idea, Carli, and yay for more choices in tops to
    put together more outfits. Now if you could just make fleece socks to
    wear inside their boots. Haha
