I've sewn the MegaMax a few times now. It's a pretty easy sew with a few options for a bit of variety. I mostly like the colour blocking which makes an interesting garment. It's also a fab stash buster.
Tools and Materials:
Pattern: Megamax Raglan from Max & Meena
Red jersey from stash
Old Black TShirt
I have learnt form experience that it is crucial that the fabric on the neck band has enough stretch. So I've used the stretchiest of my two fabrics for the neckband.
I also tend to size up, this is the 4-5 size which fits my petite 3 year old with a good amount of growing room.
I think the neckband on the MegaMax is just a tad too small so I tend to add an extra inch.
